I had another mechanics inspect my '95 E300D and he didn't catch that the front brakes weren't working. It wasn't till I came to Autobahn that they troubleshooted a clogged master cyclinder. Because they correctly solved the issue, I didn't have to pay for a new part or more labor than was necessary. I'm now having them work on my fuel lines, diesel purge, and vacuum issues. If I knew that buying an old MB Diesel would be this easy to repair, I would have got a car 5 years ago.
I also got a great price over going to the dealership on german parts (non BM), plus service was great and done the same day for rotors & pad change.
