I'd prolly buy the bike... We're only here once,eh?
I'm 70, with a bad heart, and bought my second TBA a few years back. You're right, we could go soon, and the TBA, yeah, it could use a wee bit more go power, but what the heck; it does everything just fine. I got rid of my 04 and a few bikes and years later, had to get another America. So glad I did!
Sometimes, ya just gotta ride!
Good luck with your choice!! Stay healthy!
