We had the WORST experience with these people, I would never ever recommend going to them. Not only did they do repairs that 2 other Mercedes shop's said we didn't need (they had already done them) but then after they had it for 5 weeks, and after we paid over $4000 to them the car breaks down for the things they were supposed to have fixed! They changed our oil, and now the oil sensor is malfunctioning (never a problem before) then they said that they didn't do it, but we could pay them $600 to replace sensor (yeah right). Did I mention we have moved to Austin, so they said we couldn't take it to another garage because they wouldn't cover anything the other garage said they did (like I trust them). So we didn't take it to another garage and were going to take it back to them the next time we were in houston and then, BAM, our entire car shuts down and claims battery and gateway issues (two things they replaced). I REFUSE to have them look at this car, as I don't trust them at all, they will say they didn't break it when I know they did (did I mention neither one of these things needed to be replaced, but they did it anyways and now they have broken down). They would have to pay to tow this car back to Houston and then once fixed (which I don't trust them to do) would have to pay it get it towed back to here. I'm going to a Mercedes dealership on monday and sending them the bill, I've already spoken with an attorney regarding the matter and I am well within my rights (compare it to seeing a Dr. for surgery that screws up, you are more then welcome in that situation to see another Dr for a second opinion).
Oh and although they say they are cheaper then anywhere else labor wise, what they don't tell you is that they charge a diagnostic fee (yes, seems funny considering all cars are run on computers now) that starts at $88 and they can just say whatever they want and add it on to your bill, even though the computer tells them in 5 seconds what is wrong if anything.
DO NOT USE THESE PEOPLE, SCAM ARTISTS, WE WILL PROBABLY BE SUING THEM FOR RUINING OUR E55 AMG
Cons: Make up work, hidden charges at huge costs, didn't fix
