This beast rules the road! I have owned this vehicle for 3 years. It now has 127000+ miles on it and the only repair has been a new fuel pump. I have replaced the brakes and other regular maintenance stuff. The engine runs like the day I bought it and the A/C is arctic. The interior has held up nicely despite 4 kids. The exterior is still in excellent shape. No rust anywhere. I absolutely love this truck and have already bought another 1999 for my wife.
My Dad bought my suburban new and put 170,000 miles on it. He replaced the fuel pump and the transfer case. I bought it from him and have put another 40,000 on it. I've replaced the starter and the transfer case(again). At 210,000 it still runs great, drives down the highway like a dream and gets 18mpg on the highway. I'm not going to downgrade to a smaller truck/suv to increase the mpg's by 3! When I wax it, it almost looks new....almost. I plan to take it to 300,000, the best part, no car payment, I always remind myself of that when I'm filling up the 40 gallon tank.
I bought my 4 wheel drive 3/4 ton Burb used and was concerned about the reliability. Fortunately my concerns were unfounded. I frequently tow a heavy Jeep on a full floor metal trailer through the mountains and the 454 ci just growls along. I have not had any mechanical problems whatsoever although it uses alot of brakes and I replaced the factory ones with cryogenically treated slotted rotors and use $120 kevlar/ceramic pads. They don't last long but they stop this behemoth quick and straight. Bottom line is I wouldn't trade my truck for any vehicle. It is a towing animal plus I can haul 6 passengers and a ton of luggage!
I bought this car in 2001 with 80,000 miles on it. It has been one of the most reliable cars I have ever had. I am so impressed with the Suburban, that I wax it once a month. I now have 237,000 miles and it still runs like a champ! Believe me, I got a great car!
