I think your are right Mike. 65's are faster and very cool.
Although a 64 convertible, tripower can bring big dollars as well.

Back then the 66' was the most popular model ever made for GTO's and I think one of the best looking. Possibly only second to 69's.

I am not sure about 70's comment though. 69 GTO's and Judges bring much higher dollars then 70's. Most people consider 70's to look a little too much like Firebirds, at least thats the complaint I always hear. I personally like em' all

As far as performance goes, every body who is NOT into Pontiacs...thinks that all the GTO's just came with 1 engine. They think its a 389. This is partially due to the HUGE success that Pontiac had branding the image of tripower and having a top 4 song that sold over 2 million copies,with the lines "3 deuces and a 4 speed" didn't hurt either.

These same people assume that the later years of muscle cars,1967+ could now defeat the GTO. And this would be true, except for 2 things. The GTO engines also evolved just like everybody elses and if you wanted to you could order a GTO that had all the best factory options and gear ratio's and you could be pretty competitive. BUT most people didn't. However most people didn't with the other brands either. Consider this:

Plymouth sold 1571 "street hemi's" in 1966. Dodge sold even less. Streetable...very loose usage of the term here, if Mopar didn't purposely name it the "street hemi" nobody would have assumed it was.
Meanwhile Pontiac SOLD 96,000 ++ GTO's ... 33,000 with tripower!!
