The data behind it

The market, recorded daily.
For 8 premium brands.

Every day, MarqueScope records the vehicles publicly offered by more than 5,500 active dealers in over 40 markets, plus hundreds of new private listings every week, and turns them into market analyses for the premium car trade.

Over 40,000 vehicles currently monitored. More than 50,000 documented sales. All key figures are based on 911FINDER Market Monitoring & Analytics (MarqueScope), 911FINDER's own continuous market survey.

Porsche 911 & 718FerrariLamborghiniMcLarenMercedes G-ClassBentleyRolls-RoyceAston Martin

1,068 model variants across 130 model series, from Zuffenhausen to Maranello. Dashboard market data is refreshed every 2 hours. The key figures are deliberately rounded conservatively and checked against the database regularly. You receive analyses and prepared facts, not third-party raw data.

The difference in everyday work

From 3 hours of research to 5 minutes.

You trade in six-figure vehicles. Every misjudgement costs margin, and so does every day a car sits unsold. MarqueScope replaces the legwork, not your experience.

Without MarqueScope

  • Clicking through portals, dealer sites and auction listings one by one
  • Only generic filters such as “air conditioning” or “winter tyres”
  • Sales figures in which every relisted vehicle counts as a sale
  • No idea what actually sold, or how long it took
  • Picking equipment details out of listings by hand
  • The same vehicle listed several times without you noticing

With MarqueScope

  • One dashboard for 8 brands and over 40 markets, refreshed every 2 hours
  • Model-specific equipment filters, each option with the number of matching vehicles
  • Sales counted net of relistings: each vehicle counts once, when it actually leaves the market
  • Documented sales with final price, days on market and every price change until the car left the market
  • Buying opportunities with purchase signal and open reasoning, checked before every recommendation
  • Duplicates detected across sources, so every vehicle appears once
Features in detail

What MarqueScope actually does.

Six areas, one vehicle detail view, one goal: the right buying decision. The blocks are named after the areas in the application, so you will find everything again after logging in. All views come from the live system; the figures are snapshots from the day they were taken. The screenshots show the German-language interface.

01

Today: What has moved since yesterday

The start page shows four numbers, each clickable: new buying opportunities above your threshold, price cuts in your searches, vehicles from your watchlist that have sold, and new listings matching your search alerts. Below them: the top buying opportunities that have passed every quality check and, kept separate, the review list: listings that look conspicuously cheap but are not confirmed. Nothing on that list ever makes it into the top buying opportunities.

  • Matches for your buying profiles: vehicles that fit your search profile, have passed every check and are priced below the maximum purchase price from Evaluate
  • Market pulse with active listings, model median and sales over the last seven days, net of relistings
  • Every entry with its reason and a direct link to the original listing

Find: The vehicle market for 8 brands

Active listings, sold listings, live auctions and auction results in separate tabs, so bids never get mixed up with market prices. Once you have chosen brand, model series and model, MarqueScope compares the price, equipment and market position of every listing against matching vehicles. The equipment filters are model-specific: for Porsche, for example, Clubsport, PCCB, front-axle lift, bucket seats, PTS; for Ferrari, carbon racing seats, lift system, Tailor Made. The number next to each option shows how many vehicles have it.

  • Per model at a glance: buying opportunities, market position, median, mileage, days on market, new arrivals in the last 24 hours
  • Price history per model variant, from 30 days to one year, right inside the search; for classic models, a reference line from valuation dates is added
  • Search by VIN, keyword or dealer name; saved views; search alerts created straight from the filter

03

Vehicle detail: Every recommendation explained

For every listing, MarqueScope shows the purchase signal and how it was derived: price gap to the comparison median, equipment against the market baseline, sale probability after 14, 30 and 60 days, and the selling dealer's performance in terms of sales rate, days on market and active stock. The result is a clear next step, such as negotiate or check the equipment. Plus the price history since the first listing, the VAT status and a price comparison with other European markets for this exact vehicle.

  • Quality checks before every recommendation: model assignment, comparison basis, damage scan, mileage
  • Target selling price and fair market range by mileage band, where enough comparable vehicles exist
  • Watchlist, vehicle comparison, report and search alert straight from the vehicle view; every result with a direct link to the listing

Evaluate: What is the most you should pay?

Brand, model series, model, first registration, mileage, target margin. The answer comes with a step-by-step derivation: median of active comparable listings, narrowed to those close to your mileage, median of documented sales in the last 90 days, expected selling price, minus target margin, holding risk and reconditioning. Every line states its sample size; the result carries a confidence rating and the model's typical selling time.

  • Sales basis net of relistings, with the number of confirmed exits
  • Measured euro effect of individual options as soon as there are enough adjusted sales per option; where the basis is missing, MarqueScope says so instead of estimating
  • Target margin of your choice; typical selling time per model shown right in the result

Watch: Watchlist and search alerts

Save individual listings to the watchlist and see when they sell. Search alerts are rules built from your filter: brand, model series, model. Add a target margin and a potential threshold, and a search alert becomes a buying profile that every new listing is checked against automatically. If you wish, MarqueScope sends new matches via Telegram, without you having to open the application.

  • Rules active or paused, adjustable at any time
  • Telegram connected in one step, a message for every new matching listing
  • Matches also appear on the Today start page
  • Every watchlist entry carries a status from new through enquired and negotiating to bought, plus a note and a follow-up date

Inventory: Your vehicles against the market

Enter your dealer names exactly as they appear in the listings. MarqueScope finds your active listings across all sources and compares them with the market: price position against the median for comparable mileage, days on market, and where action is needed, with a target price.

  • Price cut recommended, slightly above market, or in line with the market: for every vehicle, with reasoning and target price
  • Inventory value, price position and action needed at a glance
  • Vehicles that need action come first, so nothing gets overlooked

Market: The big picture in four layers

Overview with three market answers: prices, listing flow, sales pace. Opportunities: buying opportunities, price cuts and new arrivals. Market structure by model series, model, country, price segment and dealer. Expert analysis: selling time per model, market days supply, regional price differences, seasonal and colour effects. 18 modules you can switch on or off (as of September 2026): you see exactly the tiles you work with.

  • Price movement by model series and model, with number of listings and price reductions, median selling time and listing flow over the last 7 days
  • Dealer structure with a rating based on sales rate, days on market and price adjustments; colour effect on price, adjusted for model year and mileage, with the sample size per colour
  • Seasonal price effect still being built up: the data grows every month, and a full year will be available from 2027

What it costs, what it returns

One deal pays for the annual subscription.

The math is short. Over a year, the subscription costs twelve monthly payments. Set against that the margin on a single vehicle you buy better, or a bad buy you avoid altogether. As an example we assume a margin of €12,000; use your own figure, the logic stays the same.

€7,188

Single per year, 12 times €599

€10,788

Multi per year, 12 times €899

1 vehicle

with a €12,000 margin covers both

Put differently: divide your annual cost by your margin per vehicle. The result is the number of vehicles per year on which MarqueScope has to make the difference. At a €12,000 margin, it is less than one. Everything beyond that is profit, and you can cancel any month.

“MarqueScope does not replace your experience. It backs it up with evidence.”

Who is behind MarqueScope

From the workshop floor to market data.

Thomas Ottenstroer, founder of 911Finder and MarqueScope

Thomas Ottenstroer

Founder · Technician, former workshop manager and market analyst · Fehmarn, Germany

MarqueScope grew out of the market monitoring system behind 911Finder, Thomas Ottenstroer's independent Porsche 911 buying advisory. What has powered pre-purchase consultations, price reports and digital audits there for years is now available to dealers as a platform in its own right: the same documented sales, the same days on market, for 8 brands instead of one.

The sales medians in the 911finder price reports come from the MarqueScope SOLD archive. What you read there as a report, you use live with MarqueScope.

Short answers

Frequently asked questions

Where does MarqueScope's data come from? +

Every day, MarqueScope records the vehicles publicly offered by more than 5,500 active dealers in over 40 markets, plus hundreds of new private listings every week, and turns them into market analyses for the premium car trade. All key figures are based on 911FINDER Market Monitoring & Analytics (MarqueScope), 911FINDER's own continuous market survey. You receive analyses and prepared facts, not third-party raw data.

Which brands does MarqueScope monitor? +

8 premium brands: Porsche, Ferrari, Lamborghini, McLaren, Mercedes G-Class, Bentley, Rolls-Royce and Aston Martin, a total of 1,068 model variants across 130 model series. For Porsche, we deliberately monitor the 911 of all generations, the 912 and the 718, not the entire Porsche range; for Mercedes, the G-Class. We add further model series when dealers need them.

What does MarqueScope cost? +

The price depends only on the number of your brands; all features are always included: €599 per month for one brand (Single), €899 for two brands (Multi), and €300 per month for each additional brand, so €1,199 for three, €1,499 for four and €2,699 for all 8 brands. All prices excl. VAT, cancel any month. Enterprise for dealer groups with several locations, custom dashboard tiles, onboarding and priority support is quoted individually on request.

Does MarqueScope replace your own judgement? +

No. MarqueScope does not replace your experience. It backs it up with evidence. The system provides market prices, days on market and equipment scores as the basis; the decision is yours.

What do I see after logging in? +

Six areas: “Today” shows what has moved in your market since yesterday. “Find” is the vehicle market with model comparison, equipment filters and price history. “Evaluate” gives you the maximum purchase price and how it was derived. “Watch” holds your watchlist and search alerts. “Inventory” compares your own listings with the market. “Market” is the dashboard with price movements, market structure and expert analyses. From every list you can open the vehicle detail with purchase signal and reasoning.

How does MarqueScope count sales? +

A sale is counted only when a vehicle actually leaves the market. If the dealer relists the same vehicle, that does not count as a sale. This adjustment underlies all sales figures, selling times and the Evaluate area, and every analysis states the number of confirmed exits behind it.

What does median mean? +

The median is the middle value: half of the comparable vehicles are more expensive, half are cheaper. Unlike the average, it is not shifted by a single outlier listing, neither a fantasy price nor a bait offer. That is why market position, buying opportunities and Evaluate work with the median, and every figure states how many vehicles stand behind it.

For which models are equipment effects shown in euros? +

For models with enough adjusted sales per option. The effect is measured from actual sales, not estimated from list prices. Where the basis is missing, MarqueScope says so instead of inventing a value. With every additional sale, more models and options are added.

How does the demo work? +
