Having owned a couple Merc's I'd thought I'd share my experience of the completely crap service I've received from them and the faulty cars. I booked my CLK in for a problem with the rear headrests not dropping down (it works on pressure and something had stopped the pressurse switch working) - I first reported this decemeber when it went in for a service. The car was returned 3 times after that to fix things that should have been fixed in the service (the service cost £633!!). The part for the headrests was ordered, cancelled, ordered again, lost and re-ordered. Not once did the garage call me, I had to call them all the time and I never had a phone call returned. Now it's currently in being fixed. When I dropped it off I asked them to look at a problem with the gear box. Which a couple of weeks ago I took the car down and asked them to look at, the guy was fairly dismissive and said it wasn't a big problem, probably a management issue. Anyway having chased up my car (note: they did not ring me to discuss) I found out they have ordered a new gearbox because the car is undriveable with the current gearbox. All this may sound biased and one sided, trust me it's not. Buy a merc, sure you do get a very nice car and it's good to drive. The service however..... On the plus side, the car is just in warranty on 58k miles.
