Change the oil
I got the blue one when it had 33,000 miles on it. Every 3,000 miles I change the oil and filter with a high quailty oil. I don't baby the car, but I don't beat it either. I change the timing belt every 60,000 miles. You need to find one that was well taken care of and continue to do so, and it should perform well. I have replaced the clutch, but the worst item to replace was the heater core what a job. I hope you find one, I saw there was one for sale on E-Bay. Search for "turbo coupe" Good luck in your search. Mike
