I have 200K on my 86 740. Recently a few items have made it necessary to tow the car. So I am wondering what else I should replace to make it as reliable as in years past. So far, I have replaced: the fuel pump relay, the distributor and hall sensor, the power stage, the clutch cable. I will soon replace the radiator (origional). I thought about the radio supression relay, but don't think that my car has one (or at least it is not under the hood.) What else can stop my 740?

Thanks,
Steve
