I'm new to Mercedes but am going to buy a 300CE. Anyway, Most of the early 90's models I have seen are right at, or above 100k miles. How many miles can you usually get out of the straight 6 engines? Are they like a lot of American cars the start to crap out at 120k+? How about the computer functions of the car, are they prone to going out on high mileage cars? Same question about the transmissions. I appreciate your help on this.
