Completely unrelated picture.
Test drove a 2018 Mustang GT Premium Performance Package with 10 speed auto and active exhaust.
The increased recline compared to mine is fun, but it honestly didn’t feel any faster. 10 speeds is way too many speeds. The shifting felt more harsh than I would think it needed to be, and even when it was trying to be smooth it didn’t feel particularly fast. Faster than a manual, sure, but meh. Sucked all the fun out.
I see no reason to get an 18 over a used 15-17. Get a used Premium GT PP for under 30k, throw on a catback exhaust and some decent tires, and have fun with $10k in your pocket. Or better yet, get a used GT350, though I haven’t driven one on the street.
