Pontiac had its troubles in the '70s, but they weren't obvious in the big, lush 1975 Pontiac Grand Ville convertible. It was no '60s "Wide-Tracker," but it would be the last open Poncho for a dozen years.

The full-size 1975 Pontiacs, like the 1975 Pontiac Grand Ville, were not the eye-opening "Wide-Trackers" of the '60s. A decision to outproduce and "out-price" Chevrolet took a toll on workmanship, and luxury took precedence over performance when Grand Ville replaced Bonneville as the top-line series for 1971.

In fairness, Pontiac was struggling like all of Detroit with a rash of government rules that resulted in bulky "crash" bumpers and poor-running, vastly detuned engines that remained quite "fuelish." Meantime, convertible ranks were fast thinning, thanks partly to threatened accident rollover standards. Pontiac thus abandoned droptops after 1975 and a final 4519 open Grand Villes.

1975 Pontiac Grand Ville
1975 Pontiac Grand Ville offered a 185-horsepower 400 V-8 or optional 200-bhp 455.

As Pontiac's only '75 convertible, the $5858 Grand Ville was fairly tasteful for the Disco Age, and a 185-horsepower 400 V-8 or optional 200-bhp 455 provided decent scoot. But while most "last convertibles" scored much higher sales than the year before, this one added only 1519. Pontiac would soon recapture past glories, but not with Grand Villes.
