NORTH PALM BEACH -- John Staluppi has spent a lifetime selling cars, so successful in his trade he boasts more than two dozen dealerships and more sales than he could count. But even he has never seen a sale like this. Staluppi was liquidating his Cars of Dreams Museum and its 115 collector vehicles in an auction Saturday. The Batmobile, the Evel Knievel motorcycle, the lines and lines of perfectly shined cars, all of them will be gone. Staluppi, 65, says he is selling everything to make the museum site, which he owns, available to retailers.
