We have a 2004 MB SL-55 with 20 miles. We brought the car in around 2010 to get the TPMS sensors looked at just to find out it was going to be an absurd amount and did not care about this. We just had an issue with the SBC braking system and brought it in again since it had a safety recall. Their response was that this safety recall was "resolved" when we came in in 2010 and will not do anything for us. We were about to buy a 2014 E350 but they just lost our business.
