"he acted like it was a big deal"

GoWolfpack ....these cars were designed to be worked on in a tent in the middle or the desert, well the 240ds anyway, but changing the injectors in your car is a very easy job:p . Adjusting the valves.... well it would be nice if you could see it done but if you ever had a desire to start wrenching on your car this is the car to start with

Its nice you found a good mechanic that you trust, bring him a donut and coffee now and then. Steve
