Iconic. lol. Those cars were pieces of junk aside from their engines....poorly built cars from head to toe.
I raced every weekend in 1990/91. The Buick Grand National guys were all over, and they were the biggest liars of all time. I wish I had a nickel for every time one of them would tell you "it's stock except for the wastegate..." then he'd run 2 seconds faster than stock and after he'd blow it up his friends would all confide that it was a big inch, super-duper engine.
