Then this MB is not so friend to work on like those old 300's ?
Well I am a good DIY guy and I do not expect to be beaten by this car. All my other's old MB never beat me. Anyway, I have this philosophy: living and learning.
By the way, how often these cars give problems for owners and how often they have leaks and other similar problems? My wife's Suzuki Forenza in less than three years the valve cover seal had to be replaced. The seal get bridle (hard) and start leaking oil from valve cover all way to the engine and from there to the garage floor.
I have most the metric tools to work on my MB cars and Suzuki but I hope not to get so many problem with this E320.
I appreciate your comments, they are very helpful.
