Hi guys I'm now decided on an C Class 220 cdi Sport w204. What I'm now worried about after scrolling through the forum is the servicing costs, some in here have been quoted £900.00 for a B service. I'm now having second thoughts, my mileage is about 6000 a year, are they long life or 12 month service intervals. Seems excessive £900 for a service. I drove one on Saturday and was quite taken with the model but having read about the service costs I'm now having second thoughts, I appreciate that it's a prestige marque but it still comes across as a bit excessive. On another note is the sport button on the dash suspension and gearbox tweaks. It seemed when I engaged the button the suspension seemed very crashy over any uneven road service. Also is the standard audio system any good, the present business unit on my BMW 1 series is ansolutely dreadfull. Should I be looking for any of the audio upgrades , don't want to be caught out again.
