I'm guessing most people buying $50k toys weren't planning on using them as daily drivers, and are/were probably financially unaffected by Covid. I'm sure it played a part in delaying some purchases, but not to the point dealers resort to knocking $12k off pleading on forums for people to take them. I also doubt that once the vaccines are widely distributed in 6-12 months that the $10k+ discounts will suddenly disappear.
They probably don't sell because the front is so god awful ugly and it looks like parts bin BMW inside (shifter, power seat controls, etc.)...nobody likes a parts bin car, especially when it's supposed to be a $50k massively hyped return of a legendary nameplate. I know when I saw the shifter I was like wtfbbq?
Covid and parts bin aside, I still didn't expect to see these languishing on lots with $10k discounts.
