Buying is certainly a smart move if you can get a solid car that has had all it's maintenance and has a decent cage... otherwise you may be buying someone else's issues. The other thing to consider is "why you want to race". Do you just want to race a competitive car in IT? Does it "need" to be an ITA car? What about other classes? Would you rather build/race a Saturn just b/c it's a Saturn (ability to compete aside)? Some folks want to run XXX car and could car less how much it costs or how competitive they'll be...
