As I was coming back from Costco this morning, I almost past by some vinatge Pontiacs. I turned around and stopped by a show sponsored by the Pontiac Oakland Club International held at the local Pontiac Dealer lot.
I didn't see a '57 Bonneville but I did see a tri-powered '58 Bonneville Convertible complete with thee original owner. He had a picture of himself standing next to his car when he bought it in 1958. I also saw a '57 Star Chief, '53 & '55 Chieftan, 2 heavily modified '62 Catalina'* built for the track, a mint '63 421cu. in. Grand Prix, a 1974(I think) Grandville Convertible, a few other Bonnevilles and Grand Prix'* of different years and numerous GTO'* of all ages. It was quite a gathering of vintage Pontiac sheetmetal. Check out their site for a show in your neck of the woods.
