Really interesting idea for a web site, except bad site design makes it pretty meaningless. It should be redesigned ASAP so that every entry require much more detail or they aren't included. In other words, 'all fields required', basic stuff for a web site.
For example already there are 350 or so Accords. What year, engine, transmission + is it highway mileage, city, or 1/4 city 3/4 highway etc.... As a result of none of these items being mandated, there is no point looking at the results.
