Your thinking about maintenance and $$ wise is good, but about
the bike which u can choose from, for transport purposes are rxz
rxk, skipper, sefera, LC, TZR.
Diff between between rxz and rxk is, RXZ is newer, nicer, problem
free. RXK is older, ah pek ah pek one, but since u like vintage, u
can try rxk and do it up till very new new and nice. RXK tough old,
but is very powerful, 120km/hr anytime one, still can go up. Cheap
somemore.
