Second Motorcycle Help

2023 Royal Enfield Hunter 350, 1,700 miles, Engine and Sump guard added, great condition ($2325)

1978 Honda CB400T, 15,859 miles, apparently great shape, new battery ($1999)

1982 Honda CB450 sc, 4,800 miles, includes saddlebags, helmet, and jacket, sitting in a garage for 3 years ($1600)

I've been riding an automatic bike for a little over a year now and I want to switch to a manual. I plan on making this bike my daily driver so comfort would be nice. I know I can always negotiate but I wanna know how good of a deal the sticker price is for what I'm getting. I don't wanna make a poor decision. Please let me know your thoughts, I'm checking out all the bikes in person later this week.

(p.s. any tips about what to look for would be appreciated)
