As you know, Newman had a successful career in racing alongside his acting career, and he was closely associated with Nissan/Datsun for a couple of decades. Nissan built special-edition Skylines bearing his signature, but it's the Z-cars that carry an even more special Newman connection. After endurance races in Porsches and Ferraris, Newman switched to a 280Z in 1978. The following year he still raced a Porsche 935 in Daytona, Le Mans and Watkins Glen, but he won the 1979 SCCA C Production national championship in this car, with seven race wins and two lap records under its belt. And the entire 1980s are peppered with races either in a Bob Sharp 280ZX or 300ZX Turbo. Nissan naturally got a lot of great advertising out of Newman's racing success.
Red, white and blue Newman cars have been featured in the limelight recently, as a Doran Racing restored widebody 280ZX was shown in a Petrolicious clip earlier this year, and Adam Carolla's 2015 documentary Winning detailed Newman's racing history. This Datsun, also wearing the race number 33 and a lot of period-correct sponsorship stickers, will probably sell for a lot of money, but perhaps that will be justified. And it comes with a lot of spare parts and memorabilia, too.
