Question on BMW 3-Series AC

hi, i test drove a 318 se and when i drove it the ac was on and was fine but when i was on the way back lots of white smoke was coming from the exhaust. the man said it was because the ac was on in parked position? is this true??

Having the A/C on while the vehicle is parked will not cause the engine to smoke. The smoke could be from an internal leak in the engine.

White smoke from a warm car is almost certainly an indication of a serious problem.

Shop elsewhere.
