The $159 pre-purchase is worth the money, b/c it's unlikely the used car dealer will have the maintenance records. I'd also spend the money $30 or $40 on a Carfax. Lots of times the Carfax will list repair shops where the car has been serviced. I then call those shops and see what they can tell me about the car. That being said....judging from the long list of cars you owned, you'll know if it's a good car. Nothing like an MB V8....nothing!
