I have my 1999 GMC Yukon for sale. It has the SLT trim includes leather seats, center console, rear air, etc. It has a Whipple supercharger well tuned and was rebuilt 4,00 miles ago. It has a Hypertech transmission tune, water injection, and air springs in the rear with an on board air pump. 114,000 miles, black in color, 2001 Chevy wheels. Runs and drives great. We are starting to make big trips with a big trailer and thinking on going diesel. PM, e-mail, or call 507-437-6277 ask for Daryl. Located in SE MN.
