Great win and nice ending to the 1990 Cart season for Danny Sullivan. Sad to see him leave the Penske team. You could tell he was very emotional about the situation in the winners circle. This was a fun race to watch.
What a cool dude and class act Danny was (and I'm sure remains.) You can tell how much those six years and working with his team at Penske meant to him. Racing careers are always full of 'what could have beens' but you really have to wonder how different his career would have gone if he hadn't lost that piece of aero work and had that crash in practice at Indy in '89 where he broke his arm causing one DNF and two missed races, and then a battle to return to form. He was odds on to repeat as champ for the year, and who knows. Endless bad luck with breakdowns in '90, and then he got stuck in that horrible Alfa for Patrick in '91 and a political mess where he was treated like the poor stepchild to the Golden Boy Little Al at Galles in '93-'93, ending in them f-ing him by releasing him in winter '94, making it intentionally impossible for him to get another drive. Regardless he had an incredible career and remains the favorite driver of anyone I know that was an Indy Car fan as a kid during this era, including me.
Since his accident he had to re-train himself. He was a left foot breaker as opposed to doing everything with his right foot like everyone else from this era. Mostly because he lost feeling in his right foot. He got better in '92 but was aging like Mario.
One of the March 90P's has been in the IMS museum both times I've been there (1992 and 2015) so maybe? The Porsche museum in Stuttgart has the Porsche-built Typ 2708 that only ran at the end of '87 before they decided to partner with March for '88-'90, though it's confusingly painted in the livery of the March 88C they ran in '88. That might be why almost every racing blogger who tries to tell the story of the program 30 years later seems to think "Porsche 2708" refers to all the cars, not just that very shaky first attempt.
