The red one? Nothing really -- Needs a new battery and the clutch cable could stand a lube. Tires have to be filled about once every couple of months or they go flat. It's actually in great shape - about 110K original miles, sweet original engine (low port) that's been taken care of. No pop out. AZ car originally, so jobs like putting doing the rubber in the suspension was beyond easy... Has hyperco / agx combo in there too.
I don't drive it because I really, really like the black one. Stock from the factory with no ABS and no sunroof, and she's black. In a lot of ways, the red one is really the better car.
