The Car Portfolio Tracker for Collectors
Track the market value of your entire car collection in one portfolio. DriveIndex updates each car's value every day from verified auction results, shows what's appreciating and depreciating, and projects where your collection is headed — so you always know what you're holding.
Start tracking your collection →Your whole collection in one place
Add every car you own and see your portfolio's total market value at a glance — no spreadsheets, no manual price-hunting.
Updated daily from real sales
Each car's value is recalculated from verified auction results across Bring a Trailer, RM Sotheby's, Gooding, Broad Arrow, Mecum and more — not guesses or asking prices.
Appreciation & depreciation tracking
See which cars in your garage are gaining or losing value, how much each has moved, and your collection's overall gain over time.
Value projections
DriveIndex's Value Signal projects where each car is headed 1–5 years out, so you know what to hold, buy, or sell.
Best time to buy and sell
Seasonality analysis shows the months each model historically sells highest and lowest — time your moves with data.
Price alerts
Get notified when a car on your watchlist sells or a new listing matches your criteria.
