2015 was a banner year, nearly 35,000 sold in the USA. Only about 19,000 last year. Estimates from a number of years ago were of about $10,000 profit on each sale

So you're saying the Corvette is a flagship model that loses money for the parent company (unless their entire R&D is less than $20 million)

Perhaps that's what Apple sees in the Mac Pro as well.

Corvettes are good value when compared to the competition.

Because they’re sold at a loss?

Depends. In this analogy is GM’s only other offering a golf cart that requires an external engine to perform like a car?
