New vs pre-owned, getting exactly what is wanted as a total package considering the expense as far as engine, color, stripe, etc., etc. The close reasonable match to desires might also be too far away to easily/personally inspect and transport, another expense.

SPF as well as others continue to refine their products.

Probably some of the same reasons new Mustangs, Challengers, etc are bought new, rather than pre-owned. I bought my Z06 new, but got exactly what I wanted.
