I was looking to buy a 1988 300E yesterday and the seller showed me a car that appears to have a slight issues. He can start it up the first time and the engine runs and everything, then we tried to take it for a drive. He shift it into gear D and the engine cuts out. After that he can't even start the car. It would crank and crank but won't start up.
Is this a known problem? Is it expensive to fix. Of course he is selling it as is. The cars body looks good and has only 150000 miles.
