For the Pontiac Grand Prix, 1990 brings a mixture of business and pleasure.The business is to be found
in the advent of a
sedan version of this popular midsize coupe, a must development at a time when the baby
boomers» reproductive patterns are making midsize four - door
sedans increasingly popular.The pleasure is to be found
in a new plaything called the Turbo Grand Prix Coupe, a 205 - horsepower hummer that likes to make its great big tires squeal like babies.The business of the
sedan and the pleasure of the turbo coupe will be combined this spring when Pontiac introduces the Grand Prix STE Turbo, which is a
sedan with the turbo coupe's hot engine and
sport suspension.
