1) It's premature for anyone to assume they know how the cars will be allocated, and what that means for who gets them and at what price.
2) At a ~$375k base MSRP, the car would be expensive, but nowhere near expensive enough to scare off 250 would-be buyers a year. If Ford wanted to, I'm pretty confident that they could sell the entire U.S production run to Ford dealers that would keep the car for themselves forever.
Nearly 2,000 LaFerrari, P1, 918 will have been moved at $900k - $1.5 million in 1-2 years. And all those cars trade at a premium, with LaFerrari going for well over $2 million. Obviously different cars, but it just illustrates how much the ultra high end performance car market has exploded.
Lamborghini has produced 4,000+ Aventadors since the car's release. FOUR THOUSAND! A very basic Aventador hits right at $400k. A loaded up roadster is ~$550k. A loaded up 50th Anniversary roadster which sold it's 200 unit run quickly could go well over $600k. It's taken 4 years and 4x the amount of units for that market to finally soften, which it just now has. And everyone knows they will continue building many more of them, plus whatever inevitably follows it.
Ultimately, barring global economic catastrophe or the car being a nightmarish disaster (in which case you won't want it anyways), I find it pretty unlikely the car ever trades significantly below the MSRP.
3) The performance will justify the price. It's not going to be the fastest straight line car, but it is a weapon of mass destruction for sustained beating on a race track. I look forward to the first time it is compared with a 488 GTB.
