Under $5000, definitely. I would expect to pay around $10k for a 540 or 740 that I would be happy with. Although while I consider myself an enthusiast and fairly knowledgeable about cars, ultimately I prefer light mods and relatively easy maintenence. But yeah, a 6-cyl in the ti would be the ultimate. While we're fantasizing I might as well drop an S50 in my E30 and be done with it
