I am not familiar with 1988 190E's I have an 90' 300se . I have a few questions about these 190E's I hope someone can answer them. Doe they have timing chains or belts? Are they good on gas? Reliable? What problems do they usually have? What should I look at closely before I buy this car? This car has 136,000 miles on it and its here in Houston. I hope someone can answer these questions and help me out. Thanks...
