You only live once.
Get the manual if you can hack it. Enjoy it for as long as you can. Should it become a burden, trade it or sell it and buy whatever makes you happy.
I’ve had USAA for nearly 50 years. It would cost me another $600 more a year to exchange my '18 Jeep Wrangler JK Unlimited Rubicon Recon for a 2024 Mustang GT. I live in a metro area where traffic enforcement is virtually non-existent and stop lights are viewed as mere suggestions. Gee, maybe...
I blew it by test-driving a really nice '23 with the Performance Package. It was used, with a manual and Magneride, no active valve exhaust, and about 1,300 miles. But I snoozed and lost. Ah, well. I really liked the suspension.
Joining from AZ. My last Mustang was an '87 GT 5-speed, white over silver with the blue trim stripe. Bought it new. It was a lot of fun to drive...I've never forgotten it. So I'm shopping and learning.
