Just in time for Pebble Beach, Cars That Matter is rolling out a price guide that can give you the current collector value for hundreds of cars on your java-enabled smartphone or PDA.

If you're a collector you've probably researched the catalog and car you want to bid on before you take your bidder number. But what if a 1968 Checker Wagon in good condition and with the Factory Taxi option -- just the one you've been looking for -- is added at the last minute? How do you know how much to pay?

The guide gives you Checker prices broken down in three tiers for the sedan and the wagon, ranging from $7,200 to $20,500. It also lets you know to add another $3,500 for the Factory Taxi option, and a further 20-percent if it were a 1970-71 with the V8. It's the kind of tool that might help you never pay too much for a classic car at auction again. Or, at the very least, you'll know ahead of time that you're about to take a bath on that yellow submarine...
