1964 Pontiac
GTO
To be perfectly honest, the 1964 Pontiac GTO is not everyone's cup of tea. Designed as a piece of performance machinery, its purpose in life is to permit you to make the most of your driving skill. Its suspension is firm, tuned more to the open road than to wafting gently over bumpy city streets. Its dual exhausts won't win any prizes for whispering. And unless you order it with our lazy 3.08 low-ratio rear axle, its gas economy won't be anything to write home about. If all this dismays you, then you're almost certainly a candidate for one of our 27 other Pontiac Pontiacs and Pontiac Tempests. (Most peopie are.) But if you're tuned in to our particular wave length, if you start vibrating when you're at the controis of a sudden automobile, if you've driven enough different kinds of performance to know what it's all about, then you've got GTO written right across your forehead.

Heavy-duty coil springs have wheel rates of 90 and 110 pounds per inch, front and rear. Diameter of stabilizer bar is 0.938".

That high speed red-line tire again, this time with our optional custom wheel disc, complete with spinner and brake cooling slots.
And, to contain your change of gear-3-speed, 4-speed, or automatic transmission-the optional console with lockable glove box.
We call these exhaust splitters. A pair apiece for the dual exhausts, lurking just behind the rear wheels on each side of the car. A dealer-installed option.
