Bought my 2004 H2 in 2006 with 32,000 miles. Got an extended warranty though GM for $1000 which covered 3 yrs or 30,000 miles with $100 deductible. I had a bunch of repairs done under the warranty....you can check some of my previous posts for details....powersteering, water pump, ww wiper, ex manifold bolts, pitman and tie rods. broken shifter wire, leaking diff seal and a few other things. Fixed water leaks myself. The truck already had the updated outside mirrors installed and I'm not sure what other repairs the original owner had done. I now have about 53,000 miles on the truck and have had more repairs done than alot of other Hummer owners. But I have read where some owners have had more done than me. The warranty has recently expired, but hopefully I have corrected most of the main problem areas. The ext warranty saved me a bunch of $$$, but each truck....and the way it is used is different. Some owners have never had to do more than routine maintenance...filters, lube and fluids.
It's a tough call, but was worth it in my case. "Pay me now or pay me later"
Good Luck with whatever you decide to do.
