The Pontiac was a DOG!! And if you recall, the EPA estimates of the era were out and out LIES. The only way that vintage 'bird got 27mpg was down a hill with a tail wind and in neutral. 18-20 was more like it. It was just too dang heavy .

There were a couple in town owned by guys that thought they were hot until they saw the taillights of my Turbo 4 Mustang 'Cobra'. That little red 'stang would get 19 around town and 26/8 open road - but it was only an OHC four cylinder with a carburetor and early DuraSpark ignition. The sticker said 24 and 30 mpg
