Trust me I did this same scenario a few years back. Sold my 07 b/c I have a 62 also, and thought having something “more DD” would help, but it didn’t. Then switching back into my current 200 cost me more, but I’m settled and learned my lesson.
That’s lesson is keep what you like and love if you can afford it, and just enjoy it. Life’s too short. I’m blessed & fortunate to have this mentality for sure.
I agree with everything you stated.
