How Driveyart collects and calculates its data

Driveyart brings the supercar listings of mobile.de, AutoScout24, AutoScout24.ch and PistonHeadstogether in one search, and keeps track of what happens to them: prices, price cuts, sales and the time a car takes to sell. This page explains where those figures come from and what they do and don't tell you.

Last updated 2 October 2026.

Sources

The listings come from four portals: mobile.de, AutoScout24, AutoScout24.ch and PistonHeads. Between them they cover sellers across Europe; most of the cars are offered in Germany, Italy, Switzerland, France, the Netherlands and the United Kingdom. Driveyart covers 8 brands (Audi, Mercedes-Benz, Porsche, Ferrari, McLaren, Lamborghini, Bugatti and Aston Martin) and 124 models.

Driveyart doesn't sell cars and doesn't publish listings of its own. Every car links to the original advert; photos and descriptions belong to the seller and the portal. What Driveyart adds are the matching to model and type, and the market figures.

How often the data is refreshed

• mobile.de: a full search every night.
• PistonHeads: a full search every morning.
• AutoScout24 and AutoScout24.ch: a full search every four days.
• Every six hours, a batch of AutoScout24, AutoScout24.ch and mobile.de listings is checked on its own page: still for sale, or removed? Listings that have dropped out of the search results go first.

Listings have been tracked since 5 July 2026. mobile.de was added on 2 August, PistonHeads on 7 August and AutoScout24.ch on 11 August 2026.

Matching a car to its model and type

The model a portal gives a listing (for example “458” or “911”) decides which model page it appears on. Within the model, each car is matched to its exact type, such as the 458 Speciale or the 911 GT3 RS. That happens with rules on the year, power, body style and title of the listing, or by comparing the power, engine and year with the types in the catalogue. When neither gives a clear answer, the car is listed as “Other” instead of being guessed.

When the specifications of a type (years, power, engine, body style) are added or corrected, they are checked against the manufacturer or, when there is no factory source, against two independent references.

Prices

• All prices are asking prices, as the seller lists them.
• Prices in pounds (PistonHeads) and Swiss francs (AutoScout24.ch) are converted to euros at the European Central Bank reference rate of the day they are collected.
• Cars with price on application, and listings without a price, are left out of all price figures.
• Driveyart uses medians rather than averages: half of the cars are cheaper, half are more expensive. One exceptional car doesn't move the figure.
• A price cut is a lower asking price for the same listing than the one before. Asking prices have been recorded at every visit since 5 July 2026.

When a car counts as sold

A car counts as sold when its listing disappears after at least 3days online. Listings that disappear sooner are nearly always taken down and placed again, or duplicates being cleaned up, so they don't count.

A car that comes back within a month doesn't count either. If the same seller lists the same car again (same model, year and mileage within 100 km, price within 15%), the old listing is a relisting, not a sale. For a dealer, the same seller means the same company name; for a private seller, the same town.

The time to sell runs from the day the listing went online to the last day it was seen. AutoScout24 and PistonHeads show when a listing went online; mobile.de doesn't, and counting from the first day Driveyart saw a car would make it look newer than it is. So days to sell come from AutoScout24 and PistonHeads listings only. Where a portal gives no date, days online count from the first day Driveyartsaw the listing and carry a plus (“12d+”): the car has been online at least that long. The sold price is the last asking price, which is not necessarily what the car sold for. A listing can also disappear because the seller withdrew it.

Market history

Every night, Driveyart records per brand and per model: the number of cars for sale, new listings, sales, the median asking price, the median last asking price of the cars sold, the median time to sell and the number of price cuts. Days are calendar days in Central European time. The last seven days are recalculated every night, because a sale is sometimes detected a few days after the last sighting.

Because sources were added during the summer of 2026, the charts show more cars from August onwards; part of that rise is the new sources, not the market. The market reports only compare periods with the same sources.

Duplicates

The same car is often for sale on more than one portal. A mobile.de listing that matches an AutoScout24 listing on price, mileage and title is not added a second time. AutoScout24 also shows cars from dealers in Luxembourg on its French and Belgian sites, as copies under the name “AutoScout24 Luxembourg” with that country's VAT in the price; Driveyart keeps only the dealer's own listing. In search results, identical listings (same title, price and mileage) from different dealer accounts are shown once. Other duplicates, for example between PistonHeads and AutoScout24, can remain and then count twice in the market figures.

What the figures don't tell you

• Asking prices are not transaction prices.
• Only cars on 4 portals are counted. Auctions, private sales and dealers who only sell through their own website are missing.
• For models with only a few cars for sale, one listing can move the median a lot. Model pages and reports show how many cars a figure is based on.

Corrections

Wrong matches are corrected in the catalogue and the matching rules as soon as they are found. A correction applies to all listings of that model, including cars already sold.
