Pontiac's got quite a reputation for thinking ahead.  But we should make it clear that we don't change just for the sake of change.  We looked to the future in designing our Firebirds, for example, just to give you better cars right now. Take the basic 'Bird.  You don't have to be a designer to see that the styling is futuristic.  And futuristic styling is merely the beginning.  The roof is really two roofs - a double shell construction.  It does quite a job of absorbing sound.  Firebird's foam- constructed seats never lump.  And the ride, Boulevard smooth. Esprit is set apart by some pretty nice chrome accents, emblems and wheel trim rings.  Inside there's an assist strap on the dash.  Thick loop-pile carpeting.  A squeezable soft Custom Cushion steering wheel. Special, perforated-vinyl upholstery on the high back bucket seats.  And an extra measure of sound insulation. Formula Firebirds are our performing Firebirds.  Compared to Esprit, they're not as smooth riding.  But they are unexcelled when it comes to roadwork.  Every Formula Firebird is a showcase for Pontiac performance know-how. Lots of cars aspire to the stature of Pontiac's Trans Am.  But they'll never make it.  Because everything Pontiac knows about enthusiast driving is standard.  Because Trans Am was built to be the ultimate Firebird.
