Nice Grand Am, looks great! I love the 78-80s. Although my 79 is almost completely original, and is still in decent condition, it has about 80K more miles on it than yours. It is oddly optioned too (sign of the times, when you could order almost anything you wanted), I just got the PHS on it last week. It has the 79-80 GA & GP only wire wheels, automatic climate control, power glass sunroof, PW, PDL, RWD, tilt, limited slip, and Rally RTS handling package, and deluxe velour int. BUT it doesn't have a console, gauges, or cruise control.
Anyway, always great to see another 78-80 Grand Am, thanks for sharing.
