I've found a 1990 Celica All Trac for sale for $5000 w/ 121k miles on the ticker. According to the guy that's selling it, he's installed an HKS turbo timer, Greddy blow-off valve, and an ACT clutch, as well as changing the timing belt, water pump, spark plugs (Denso iridiums), radiator, thermostat, and water hose. The only problem is that he says the car still overheats occationally. What are your views on this? Blown/leaking headgasket? Is $5k worth it for this car? Here are the pics he sent me:
