Car appreciation... the aesthetics, the engineering, etc

I'm possibly after a 5 or 7 series BMW preferably from the 80s or 90s, something a bit retro. Want something solid (hopefully rot free), punchy engine but reasonable to run and maintain. Would be keeping it for a few years if I found the right one.

Any ideas as to ideal model numbers please petrol heads?

E34 5 series would be my choice. manual 6 cylinder one if you can find one.
