The site is more than just where to find good prices. Today they had a Poll: when you go on vacation, do you tend to take toll roads, divided four lane hwys, 2 lane roads, etc. (Would it not depend on where you are going?) There is a section on the latest fuel or car technology news (today an article on General Motor's work on hydrogen fuel).
It also led me to another cool site: Fuel Economy, where you can find the most fuel efficient cars - and they even cover a few cars from 1985. Mostly it's the 90s to the present.
And lastly, if you yearn for us to be less dependent on petrol, you can check out Willie Nelson's Bio Diesel site. He has outlets (mostly in the south) but his bio diesel is distributed Nationwide. You can imagine it's not a stale, dry site! Willie is even selling bumper stickers and hats that say Bio Willie :-) Peace Out 3C
