01

Scan it

At a show, on a dealer lot or in an auction preview: point the camera at the VIN plate, the window sticker or the lot sheet. DecodeThis reads it on the spot, 1950s formats included.

Read it

Marcus, Jo, Evelyn and Gus each take a pass: what the VIN verifies, what to go and look at, what to ask the seller, and what it should cost.

The garage: every car scanned, grouped by where it was seen, one still sending

Keep it

Every car you scanned stays in your garage, on the phone, grouped by the show, the lot or the sale. No signal? It's saved and sent later. Share any of them to a page on this site.

Featured2024 Jaguar F-Type P450 75 Coupe AWD
Week of Oct 12, 2026 · Seen at Barrett-Jackson Scottsdale 2026

The 2024 Jaguar F-Type P450 75 Coupe AWD pairs a supercharged 5.0L V8 with an eight-speed automatic and all-wheel drive. It was built in the United Kingdom in the F-Type's final model year. Our experts point to the details that mark a true 75: 20-inch Style 5102 gloss black five-spoke wheels, limited-edition metal treadplates and the Exterior Black Design Pack. The VIN decodes cleanly and no open recalls are on record.
