Time will tell, but it’s really a matter of wanting a loaded GT+ model versus a stripper halo Shelby modelA mach fully optioned out is 70k, a base gt500 is 75k. Dark Horse may be 73k? I was cross shopping those options. I chose Dark Horse for reasons, but I can see where you may be tempted.
Any options at all on the GT500 increases the price quickly though, and I decided I wanted an optioned car, so that helped my decision.
And then on the topic of used versus new, it’s about warranties and “new car factor” personal values versus finding a clean example with hopefully a good ownership history
