I purchased my 1998 Tahoe coming off a lease with 28K miles. At 32K I found that the rotors needed to be replaced and that Chevrolet had put undersized rotors on its trucks up until 1998, and corrected the problem in 1998. Stopping distance is 50% greater than average for the Tahoe even with no passengers and no load and not pulling a trailer. I bought it to tow a trailer but with the terrible brakes I have avoided using it for this purpose. Can only use a proprietary CD player which costs 4x as much and mine broke within a year. In first 100k miles I had to replace the breaks twice, rotors once, manifold gasket, fuel injectors, AC compressor, idler, and the front tie rods.
Short wheelbase for this size vehicle. 4x6 foot space with rear seats folded down. Good visibility in all directions. Good instrument and cabin layout for driving. Plenty of space for 4 large adults and other gear. Gas mileage for a large SUV is very good with 16-17 mpg mixed driving.
Brakes and rotors need upgrading with 3rd party equipment. Roof rack is barely attached so ignore the 300 lb. rating and keep weight to under 100 lbs. New AC evaporator design makes repairs very expensive. 4x4 shifter requires driver to put head below the dash to shift in and out of 4x4. Better to buy a 1999 or newer model or better still to buy a Toyota Sequoia.
