When you know you've found a good thing, you hold on to it. This is the mindset that led Michael Argandona, of Huntington Beach, California, to keep this 1989 Pontiac Firebird Formula for three decades. He has lovingly maintained it, keeping its smooth black paint and sleek sheetmetal in immaculate condition. The result is a car that's just as cool today as it was back in '89.
