im picking up an 05 tomorrow. It seems some folks on this forum would rather say "search you idiot" and not be helpful. From what ive gathered, be aware of the suspension issues which is too long and in depth to explain here. basically the entire strut/spring needs to be changed as well as some other bushings. The one im getting has 2,000 miles on it so i will hold of a little while but dont mind doing coilovers in the near future. the engine and trans seem to be as bullet proof as any LS system, the electrical discussion seems typical of GM, some glitchs but nothing inherent.
