So the buyer is expecting to resell that car for 250k in 3 years. He is probably smoking something funny.
If you have the money and that is the particular car you want and prefer not to wait to wait months to order the same thing new and get it for a lot less, why not go for it.
I don't have 135k cash burning a hole in my pocket at the moment to buy a fun car, but if I did ... I was just looking at some previous sales on bring a trailer. How about this instead?

Oh, wait a minute, check this one out, it is under 100k and comes with a hard top.

Alright those aren't Superformance, but if a Superformance is what you prefer, what about this one that sold just about a year ago for almost 100k less than the black one sold for yesterday?

Good luck to yesterday's buyer on getting his expected investment return.
