ZERACER do you have any idea at what mileage the RCM, crank shaft position sensor and belt tensioner have been failing. The crankshaft sensor is a no brainier because its a cheep fix and I thought about getting an RCM just to have on hand but unless it was poorly made or designed I have seen belt tensioners last for years. My car has 45K on it and has always been garaged. All of the exterior rubber looks new and is soft so there hasn't been a lot of ozone, UV or prolonged hot or cold temps subjected to the car. The belt looks new also with no cracks or drying out but I might replace it just in case. Also I drove the car 500 miles home right after buying it with no issues. Anyway just looking for an opinion here.
