03 Sierra Z71 extended cab I got off a ag company with 180K and change on the odometer when I was 18. They said the tranny was slipping so they gave me a good deal on it, picked it up for 4K after I mustered up my best used car buying skills. It was from a farmer I had known for a while and he was nice enough to carry the note for me, paid him off ASAP!
I fixed and replaced a lot of parts on that truck, motor included but that tranny never failed. I beat the absolute shit out of that truck between being young and dumb and hunting. It now sits at my shop awaiting its fate with the scrap yard. Rode hard and put away wet, but some great times were had in it.
