As a quick check, I went on Autotrader, selected $4,00-$6,000, RWD or AWD, Couple or Convertible and any distance from me.
There were 21 pages of cars that showed up, although I think about half of them were smart cars. The rest ranged anywhere from a Pontiac Fiero's, Corvettes, BMWs, Camaros/Firebirds/Mustangs, 300ZX, and of course Miatas.
Lots of good choices, many of them I would buy. My favorite that I saw through a quick scan was a
87 MR2 with a "new" engine (300) miles, in Red. Sadly its an AT, though.
