It doesn't matter if they aren't 911s, you can get pretty much any car that has been recommended in this thread, in pretty good nick, for the same price as a totalled, rusty, engineless 924/944.Porsche 924/944: I've seen a few around here in the $5,000 range. No, they're not 911s, most don't even come with turbos...but they're Porsches.
Trust me -- in highschool I believed I could have a 944 for a first car. That idea changed to the 924 and then the 914 before I gave up on it.
