There's a 2005 Bentley Continental GT for $29,800. Seems like a good buy. I think someone forgot a zero? http://www.cars.com/go/search/detail.jsp?tracktype=usedcc&#3... Your app made it easy enough to find an exception like this.

There's also several cars for $299, but in the description are $2990 down...

Thats cause thats how they are classified on cars.com. Can't blame the developer. He scrapped the data correctly just some smart ass marketing guy who put up the ads cheated...

Earlier quoted context omitted.

I don't have access to OSX, it works on my Safari under Win7.

This is what I got when I tried in Safari 5.05 under Snow Leopard. Not sure if it helps since you can't test but here ya go. Also shows the errors I got in the error log console. http://img4.imageshack.us/img4/3154/screenshot20110815at134....

I think it didn't like the gzipped JS file with the data. Not sure why, pretty much all modern browsers should support it.

Downloaded 20 search results pages from cars.com. I wish I had direct access to their DB. Craigslist has a ton of car postings, but it's not structured in any way, will be very hard to parse.

Have you looked at the Vast API. http://www.vast.com/info/customapi

I will take a look at it, thanks!

Interestingly, it looks a lot like a Pareto optimal curve that is being optimized for maximum value to the seller, not the buyer.

Which would make sense since the seller sets the asking price. We don't know how much each car is actually going to sell for - presumably the buyers have more influence on that curve.
