So about 3 months ago we are just purchased brand new tires all for a struts and various audio upgrades for the trailblazer that we have but lo and behold three days after we put the tires on the motor blue so we purchased another car and said trailblazer has just been sitting it's an 02 LT White with about $250,000 miles on it I'm in between either parting it out or fixing the engine and just changing the block any thoughts on that I would greatly appreciate!
