Glad to hear that you got that car Joe, sounds like you are happy with it.
I have no idea what my oil pressure is, but its been serviced by the dealer since brand new and no indications of any engine problems. When they decided to kill Pontiac last year I got a letter in the mail from the dealer saying that they would give me free service this year except for the cost of the oil and parts, to try to keep my business. Can't beat that.
My AC compressor died this past summer and I got my "older car" mechanic to do the repairs. He told me it was the most expensive AC job he ever did for anyone- I guess suppliers figure that anyone with an LS engine can afford inflated prices for parts. But that's the only problem I've had with mine (other than the seats splitting) in the 5 years I've owned it.
I'm not sure which club you are talking about. I've started taking my LeMans to local shows and getting an idea of just how few classic Pontiacs there are in the Augusta area. And I have yet to meet another local "new" GTO owner- you are now as close as that gets
