My buddy, who owns a 1990 TGP told me about this site, and I look forward to learning what I can.
Although I own a newer 1st gen, my guess is that I will still be able to pick up useful info, on GPs in general.
The two of us just bought a 1992 SE w/B4U, and plan on repairing it and reselling it in a short time.

My car is a 1995 GTP and is currently being cleaned up from the previous owner.
I have already installed a HUD,DIC, And a factory AM/FM/CD radio.

See you around!
