Hi Carat, bing, thanks for responding. The car is an '86 300sl, it is in Ealing. The car was last driven 3 months ago when it was driven around 200 miles to bring it to my house from that of the prior owner's. It was standing in a garage previously as well per what i was told. I took it off its MOT, but will probably bring it back into use first quarter next year. I do start it every week/move it back and forth on the driveway to charge up the battery, work on it etc.
I want it checked for a number of reasons. First I have no idea when it was last fully serviced. The engine is misfiring and it doesn't sound healthy. Additionally, the exhaust has recently started billowing white smoke and water vapour although the car hasn't been driven, and the smoke smells a bit unpleasant. I would like to identify and rectify any issues asap in case damage is being done each time it is started, so any mobile mechanic type gentleman who work on it on a weekend would be quite helpful.
