Go for low miles.
Bones and I had a high mileage CX650 blow up on us on a road trip.
My first goldwing (81) blew up just short of 80K (far short of what a GL1100 should reach).
Now my 81 Virago has a mysterious knock at 22K. I haven't yet gotten to opening the engine up to figure out what broke. Anybody got a spare Virago engine?

Point is, with old high mile bikes there is no way to know how the engine was treated, or if oil changes were made regularly, or at all.
Oxidized aluminum or rusty chrome can be replaced (or embraced!). Go for the bike that is more mechanically sound, every time.
