got me a 2006 Tahoe Z71 , 71000 miles , nice ride , loaded , no pictures yet , will do some tune up next week end , spark plugs , wires ,belts all filters and fluids , check the brakes and shocks , just wondering if there's anything I should be concern about this year model , and I'm not sure if it's a flex fuel or not , and if it make any difference .I bought it with 22'' wheels , which I'm not really impress by the ride , it feel like riding a coach on pavers , so that's on my change list to probably 20'' .
