Do what? Sssoooooo...you dumped $5K of crap onto a Yukon, that you couldn't afford to make the payments on...hhhhmmmmm...Oh yeah, you're real bright!
There you go again Gerald reading whatever you feel like into whatever you read. Did you get that talent from our commander and chump? i guess I'll have to clarify myself again so you don't go and hurt yourself - I had a $50k/yr job that requires a full sized truck. Bought this cheap (cuz they stopped making the 2door by this point) - rebuilt motor and trans, custome exhaust, cd changer ect... Then some conservitive butt-munch thought that I could endanger his $365k/yr posh job so he strong armed by boss to fire me. Once fired I couldn't return the rebuild...
And since you cannot seem to understand the points I make I'll even clear the above one up as well - If this GTS is anything like my poor yukon the orginally owner could have very well taken care of the car and did everything right to before having a string of bad luck that lead to the repo (what in this economy...na..couldn't be, the right wing insists everyone's job is safe remember.... * - note sarcasm.) Is it possible that the car was mistreated? Of course, but since 75% or more of ALL used cars come from auctions your luck as this being a lemon is about the same as anywhere else.
