Hi knowledgeable people - almost time for my first 996 MOT and as it's history has but one advisory only noted, I am hoping to keep it that way and have a pre-MOT inspection / service beforehand. I normally wouldn't really consider an OPC but their fixed price deals actually look ok and Sidcup get excellent reviews. Mr 911 is fractionally cheaper and marginally closer - I know they are considered decent to deal with if buying but don't know of their rep for servicing (which seems to be through 911box). What would you do - OPC or independent (and in particular out of those two choices...)? Cheers.
