Trying to buy Predator

Hey everyone, I am trying to buy a predator off of craigslist and came across a few now. I have a Trailblazer 330 and it's getting boring so i'm trying to find a fun predator. I found an 07 that runs, has a title, and he says it is well maintained. The only problem posted is a crack in the rear and he is asking $2500. What type of questions should I be asking him? Thanks in advance.
