LS 1991 Used Automatic Gasoline mileage: 300 KM or more Suburban 454 model 91, considered a classic car. The engine is clean, does not smoke, and has no deficiencies. The transmission is excellent, with no issues. The AC is all good, it needs the air distribution fan changed as it's broken. Since I have another car, it's parked in the garage and I don't use it. I accept suitable trades.
