Step one
Paste the listing. Any listing.
Paste the auction URL and we’ll pull the listing ourselves, or paste the text: BaT, Cars & Bids, Craigslist, a text from a buddy. A year and a model is enough; a VIN makes it sharper.
Verified in the open
We don’t publish numbers we can’t back.
Every figure on this site carries its provenance: estimated, owner-reported, or shop-verified, and every one starts at the bottom of that ladder. The 996 is being verified first, against real shop invoices and owner submissions, in public. Watch the estimates become real numbers.
In the garage (cost data being verified)
BMW M3 (E46)
2001-2006The end-of-analog-era M car. The S54 is a masterpiece with two expensive, well-documented Achilles' heels (rod bearings and the rear subframe), and pricing on these cars assumes you know about both.
Ford Mustang GT/LX 5.0 (Fox-body)
1979-1993The people's American performance car, with parts support that borders on infinite. The engine is nearly unkillable. The risks are structure (rust, torque boxes), decades of amateur modification, and everything rubber being 35 years old.
Mazda MX-5 Miata (NA/NB)
1990-2005The most affordable way into a 90s roadster, with a famously robust drivetrain. The money pit is almost never the engine. It's rust, deferred rubber, and a tired top.
BMW 5 Series (E39)
1997-2003Peak BMW build quality by reputation, with a well-mapped set of aging plastic and rubber failures. Six-cylinder cars are the sensible buy; the 540i's V8 adds real cost and the M5 is its own universe.
How it works
Three moves before you wire the money.
01
Paste the listing
Year, make, model, and mileage are enough. The full listing text (or the VIN) makes the report sharper.
02
See the real cost
A prioritized deferred-maintenance list with parts + labor ranges, provenance on every figure, a headline budget number, and a chassis-specific PPI checklist.
03
Negotiate like you know
Take the $29 packet to the seller, or book a $99 call and talk the car through with our team before you buy.
