So I guess the answer to “who’d pay $70k for a Mustang!?!” is YOU. Hehe.
Seriously though, you hit it on the head: the only ppl that will pay that for a Mustang are ppl that are die-hard 'stang fans and simply must have the “best” Mustang money can buy. Most ppl w/ $70k to spend on a car simply have more refined taste and expect a lot more (in terms of performance, luxury, curb appeal, quality etc) out of a car.
