Thanks for the welcome.
1st Merc, W140 seems like a good place to start

I bought in a bit of a rush because my other cars AC blew up and not enough time and money up my sleeve to find a perfect example just now.
1996 S280 Navy blue, 217,000km's, was sold new in Singapore, barely any log entries, no reverse, decent engine oil leak somewhere (however the oil level is too high), if provoked with fast off the line full throttle the engine stutters for a half second, seems to idle a bit too low, inside of front tires scrubbing (hopefully just needs alignment!) engine temp gauge flickers at times, gear selector illumination comes and goes, light switch isn't 100% trustworthy in the off position, both sides rear view mirror bodies need attention, couple of interior rattles, seats are dried out with some minor marks otherwise looks pretty good, all electrics and AC work fine however the windows need a lube up, wind noise coming from missing 1inch portion on drivers side rubber trim, subtle but large dent low on drivers side 3/4 panel, small dent above LHS rear tail light, two other very small body dents, scuff marks and areas of flaked off paint on front and rear bars, missing LHS front bumper insert, dent in chrome under boot.
By the looks of the paint and trim it has been garaged for most but not all it's life. From all the minor battle scars this car looks to be original or has only had minor damage in its life but I did notice the lower corners of the front window have bubbles trapped under it. Not sure if that means it's been replaced or if that's the work of the factory.
IMO it looks respectable otherwise I would not have bought it. Yes it needs work but I am able to do most of it myself. With many hours of my time fixing the small problems and big mechanical problems, front and rear bars resprayed, a bit of touch up paint and some paintless dent removal I think it will come up very well.

She looks good on the picture Joe , I'm sure you can manage a few of those fixes that the car needs , the window probably just needs a new revet on the other side to stop it from falling those few centimetres down to let the air in by the sound of it .
Change the spark plugs ,filter & see if it still studder's along , how does the petrol filter rotors/rotorcap look ? .
When you say it has to much oil ,how much is to much ,how high does it go on the dipstick ? ,check transmission oil ,if that has to much in it as well,it comes back out from a valve beween the engine & transmission direction spilling oil onto the exhaust creating white smoke . :thumbsup:
