Should i buy this trailblazer to fix and sell it?

well it depends on how much profit you want after you buy it. did you check price for used engine or re-man a re-man from either a dealer or someone like jasper engine will be in the 2700 dollar range radiator will be around 200 dollars you will have to find out about the miles just because its a 05 doesn't mean less miles i've seen 05"s in my shop with 150K on them which brings kbb price down and do you plan on doing work yourself and then does nevada have a "as is" law where you don't have to warranty it and can you see the truck or is it far enough away so it will have to be towed another expense just a couple of things to think about
