5.3 liter V8 engine with 4 wheel drive. It has many upgrades such as heated leather seats, remote start, towing airbags, rough country lift kit, etc. There are 230,000 miles on it but only 100,000 on the rebuilt engine. Work done in the past 6 months or so has been a rebuilt rear differential, new rear shocks, new ac hose/orifice tube and freon. The body has some cosmetic damage but it is a well maintained and a reliable vehicle. I have owned this Tahoe for the past 6 years and have done some of my own maintenance. I can tell you pretty much anything about it and I will be honest. I originally purchased it at auction. It had a salvage title but was not in a major accident. I had it inspected after the engine rebuild and the title was restored. It has been my daily driver the entire time. No check engine lights or major issues. Cold AC.
