About “"Bud"”

In late 2005, I decided that I didn't want to subject my '66 Corvair daily driver to another winter of Pennsylvania road salt. Its floors had virtually no rust, just a little surface rust, and I wanted to keep it that way! GM was having one of its rebate promos, so I checked into how much a Cobalt would cost. The local dealers (I have three within 10 minutes!) all came in too high, but there was one about ten miles away that quoted me a price that was just too good to pass up. They pitched me the SS, with the equipment I wanted, cheaper than one of the other dealers quoted me on am LT!
I call it "Bud" because I'm a big NASCAR fan, especially the Earnhardts. Dale Earnhardt was, is, and always will be THE MAN! Dale, Jr. is currently my driver, because, after all, he is his father's son. Now, at the time, JR. drove a red Chevy SS with "Bud" painted across the hood. What else am I going to call MY red Chevy SS? (I have no plans to repaint it in his current colors!)
And for all you other NASCAR fans out there, I'm open to guesses as to what Bud's license plate "BOOG8Y 3" means.
