I finally found a car that I may want to buy, spec wise. It is a 2019 Mustang GT Premium Coupe with the 10spd, 401a, pp1, and the active exhaust in shadow black. It has a great Carfax and the owner seems great, he's getting it inspected this week at a Ford dealer for me. Is there anything I'm missing out on here or anything that I should reconsider? How much do you think I should be paying for this car? Anything you all think just let me know or ask! I'm very excited but don't want to make a bad decision due to the excitement haha!

Note-

Has 60k miles and clean title/no damage reported.

I have a 2013 g37x sedan 7at with about 135k miles. About 2 weeks ago I parked my car at work, and when I reversed, the car stalled out similarly to how a manual stalls when you mess up the clutch. I turned the car back on and it continued to do this in both drive and reverse. I thought the car would have to be towed. After work I tried one more time and gave it a bit of gas upon going into drive, I got it moving again and drove it home. Since then, it hasn't completely stalled out, but the idle in drive/reverse was very poor and seemed as if it wanted to cut out again. I did a transmission fluid drain and fill, since then it hasn't stuttered at idle in drive/reverse, or died, but it feels a bit jerky and indecisive on shifts, it also seems to rev a bit higher periodically. The car rolls just fine in neutral, and there aren't any issues in park. The car runs and drives as of right now but I'm scared to push it or drive it anymore than necessary for work/school. Does my entire transmission need replacement, is it my valve body, is it my torque converter, or could it be something else I haven't even thought of? Please let me know what you guys think, I'm not sure how much longer it'll drive and it's my daily so I kind of need it! Thank you so much in advance everyone!
