Could even be a lot less than half as much.
I don't know about other areas, but for poops and giggles I checked used Porsche prices in my area. I was looking at used, late-model 911s.
Porsches hold their value incredibly well in this area.
And, of course, new Porsches can be insanely expensive. I priced out a 911 Carrera S, with not too many options, and it was north of $125k.
Having owned both, and recently switched to a used 2014 GT, IMO a Mustang is far more fun to own.
No 911 ever made sounds as good as a GT with a nice exhaust on it, and even a stock GT has more power than a 911 or 911S.
But of course everyone on this forum already knows that, so apologies for stating the obvious.
