1991 Mercedes-Benz 300SL Problems
As vehicles age, various problems may develop with the hard and soft tops. If problems are encountered, it would be recommended to have a technician familiar with these tops perform the diagnoses.
Internal and External engine oil & coolant leaks can develop from the head gasket and/or timing cover gasket; these leaks should be repaired before the engine oil and coolant intermix which can result in severe engine damage.
Other than a defective motor, a bad switch or blower motor resistor assembly can cause an inoperative heater blower motor.

My 1991 SL mercedes is a beautiful car. When it sits for a long period, once driven, it cuts off. The car will start after sitting a couple of hours. Restart car and drives fine.
Most reliable, affordable (used car) I have ever owned. And i have had many! Maintenance is cheaper than my mini van, if you go to the right place. I go to Collie Autoworks in San Rafael Ca. Darren and Denise are the ABSOLUTE BEST. I LOVE this CAR !!!
