Built by car people.

Shifty exists because of questions every collector asks and nobody answers well. What did we pay for the Aventador? When did the Pista last go in for service? Is this dealer price fair for this color and these options? What is the 911 worth today, not last year?

Our founder is a collector. His records lived in a glovebox, a shoebox, and three email threads. The values lived in guesswork. The market moved every week and nobody called. Shifty is the tool he wanted to exist: every car, every record, and a live number you can trust, in one place.

The Shifty Estimate reads more than 96,000 real sales and listings across 2,700+ collector models and 74 makes. It weighs recent comparable sales, throws out the outliers, reads the spread between asking and hammer, and prices the specific car. The same engine powers the app, the Top 50 chart, and the free valuation tool on this site.

We are a small team that cares about chassis numbers, build sheets, and the difference between a 996 GT3 with 4,000 miles and one with 40,000. If that sounds like you, you will feel at home here.
