Hi Today I collected a 2006 C350 with 55K on the clock. I part exchanged my E39 M5. (previous cars have been an RX8, 968CS and MG ZTT plus others) So far I am really happy, its got no where near the noise or shear power of the M5 but I was really surprised how quick it is. The handling is excellent (I have the sports pack) and the engine is super smooth. Any tips for a new owner? Im looking to buy one of the bluetooth kits for the pre wiring. Is ebay the best place? I have seen them for £169.00. Is it worth getting the mark 3 so it can play songs through my ipone 4?
