how about finding by just "make"? for example: I want to find all chrysler cars from 1900-1964. Any chance you'll suppor that?
Peter, the way the site works I search for makes and models at the same time. This gives me the most 'specific results' I can get. If I leave it open ended with just the make, you'll get some pertinent and many not-so pertinent results.
Because the titles of the classifieds are inconsistent at best (you can't expect sellers to follow any set rules can ya?), the current incarnation of the site's search capabilities (and retrieval methods) are likely the best way to search.
In the future, I might add "column" based sorting. i.e., sort results by title, source, location or price.
Hope that helps...
