Just picked a 1999 Yukon with 185k. Love it! This is my first full size suv. I had a rodeo before. I am a car guy so i always had something lowered. I have a 2011 koup as well. There are a few little things like the door sag and the rear liftgate window will not lock. Tried youtubing it and found nothing. It came with 15" Chip Foose wheels and that is the only mod done to the vehicle. Looking forward to building something nice. I do want an exhaust as my first mod(after fixing the door sag and rear window locking issue). Thanks foe your time.
