hm, not sure how we'd add exclusion to the search. do you find any of the price/mileage filters useful or do you really just want to be able to say "No Hyundai" (or whatever)?
I think we'd also like to add some basic recommendation engine type stuff soon - my last car was a $500 tercel so feel you on the ubercheap classification. If we had a "Sort by Cheapest Reliable" option would that be useful?
Thanks!
