LS 1991 Used Automatic Gasoline mileage: 300 KM or more Suburban 454 model 91 is considered a classic car. The engine is clean, does not smoke, and has no نقص. The gearbox is excellent, no complaints. The AC is all good, it needs the air distribution fan changed because it's broken. Since I have another car, it's in the garage and I don't use it. The last offer in the showrooms was 10 thousand 3 days ago.
