The guy he got the car from told him that it was 1 of 700 and I went on the net and found that the T-37 was only listed for 1 year and that was 1971. It's true it is a pretty basic car. but someone may be looking for one. I remember seeing just one around here about 10-15 years ago but it was not this one.
The book i got in front of me lists a T-37 just for '71 and its not rare - try 7,184 coupes, 29,466 hardtop coupes, and 8,336 4 door sedans. The absolute rarest 72 pontiac you can have is a Trans Am coupe with 1,286 built. So dont trust other peoples 'instincts' on one of 700 built
