I didn't say I was going to sell it, but I would be reluctant to keep it once the warranty was up and I'm not sure I would buy another, the Merc dealers round here have really let the brand down. Not can only can they not service the cars they not that interested in selling them.
I had a brand new BMW X5M which developed an engine fault within 3 weeks, I rejected the car. The difference here is that BMW gave a fantastic service, they built me a brand new car, let me change the spec, gave me a brand new taxed and insured loan vehicle for 6 months while they built it.
I now feel more ****** off with Merc over a key than I did with BMW over an engine fault but that's because they dealt with it and provided good customer service.
