Going from my 2012 Overland to a 2021 Summit L, they "feel" totally different to me. BUT, I believe a LOT of that is because I also went to something that cost me $45,000 - $50,000 more in value. I think I instinctively drive it more "protectively"
My 2012 was bought as a 3rd vehicle "beater", then it got traded in along with a nicer car on the new Summit L. So the new one is both my "Jeep" and one of 2 "Nice Cars". (not that the 2012 wasn't nice, it was very nice).
In 2 months I went from

2018 Dodge Challenger 392 HEMI Scat Pack Shaker
to
New 2021 JCG Summit L
CPO 2019 Volvo S90 T8 Inscription
