i know it sounds like a silly question and my guess is no but i am considering buying a 93 300se. at 190000 miles what kind of problems am i looking at. and
1) what causes a stiff accelorater pedal?
2) when you turn the wheel to the max( till it wount turn any more) and it squeals, is that a bad pump?
3) does a car have puffs of smoke(or steam) when idleing cold at 60 degree weather?
4) what causes wheel vibration at idle even in park on these cars?

sorry for all of the questions but i need some reasurence before purchasing this car.
thanks in advance for any info you can give me.
