I bought a 1995 S600 with 120,000 miles on it last April. I've wanted one of these beautiful beasts for a long time. I fell in love with it at first sight. It appeared very well taken care of, and I still think it was. However, it's been in the shop at least 3 times since I bought it. Check Engine light, SRS light, Steering Angle Sensor, and a broken heater line manifold. That manifold problem is probably what pushed me very close to the edge. I could see no way to change it without possibly pulling the engine. I decided to let the dealer handle it. The dealer quoted a reasonable price, and about 3 days to fix it. 10 days later, I finally got the car back. The dealer said they had at least 10 solid hours of work in the car, and at $120 an hour, that could have been pretty expensive (I have to say that the dealer, Loeber Motors in Lincolnwood IL was very decent about it. They honored their quote, and they always treat me good). I'm very concerned about the repair and maintenance issues on a car like this. It's like people say...when it's running good, it's an amazing car to drive. But when it's time to fix it, it hurts. As much as I love this car, I will probably sell it this summer. I am just not comfortable knowing that such high costs for maintenance are lurking around the corner.
