That Riviera is a thing of beauty. I wonder if they had to get permission from the Corvette Division to do that C2-reminiscent back glass.
I loved the 1st and 2nd generation Riviera's, too.
Speaking of Buicks, when I was 12-13 ('63-ish), we had a '59 LeSabre in a medium emerald green... there's a kind of beauty in its awkwardness...
The old man paid me a dollar every Saturday I washed it. Year-round... used warm water from the tub faucet in cold weather. Got a dollar for washing his Ford Econoline work vehicle, too. Two bucks a week... slot racing money.
