Yesterday I went to my local dealership for the first time to pick up some parts. I didnt have high expectations after reading some of the posts on here and elsewhere, in fact i was dreading it ! So, I thought I would post some observations. 1. They had the 4 interior plastic trim clips I wanted in the right colour at a very reasonable price. Ok they will have to come from Germany, but that's fine, there's no rush. 2. The staff were polite and friendly. They had a new SL350 in the showroom, which was the first time I've seen a MY12 SL up close. 3. While i was waiting, I overheard a telephone conversation from the service area, one side of which went as follows : "We plugged the diagnostic tool in Sir, and there was no fault recorded. I understand there is a hesitation and lack of pulling power, but we can only use the tools we are given, and if there is no fault showing, there is nothing we can do". This conversation went on for some time, as the customer clearly was not happy with this response. This brought back memories of our 2007 CLK, which had similar symptoms, which brought a similar response from MB. So, I left with mixed feelings. It seems ridiculous to sell cars that can only be fixed with computers, when the computers in question are clearly not up to the job. I think the staff feel the same frustration. At the end of the day, they just want to help their customers.
