I have been searching for 6mo, trying to find a decent 01 or newer Tahoe 4x4 for the wife.
About a month ago she found a 99 Yukon SLT 4x4. It only has 190,000mi, good interior, an actual tow package not just a hitch, so I checked it out. $3000 later, it's hers. $500 worth of parts later, it now has keyless&remote start, brake controller, new ball joints, head/turn/tail lights, grill, markers, power mirrors.
We were really wanting the 01&newer with the 5.3, but considering the $, miles, and mechanical condition, we took a chance. Not to mention the guy showed me the records he had from recent repairs. New radiator, water pump, intake, distributor, coil tune up, injector, regulator, service every 3K by Firestone in Lex.
I have heard every BS line a sales man knows, and no shortage of those. I run into several 4x4s that didn't work.
I know how hard it was for us, so good luck to you.!
