Kinda agree with Chris tbh, mine now is pampered to death, ok it,s not concours BUT there,s NO rust anywhere and the underside is fantastic. BUT, i,ve be driving it more recently Ford Fair etc and i personally think they WORK/GO better when driven regualry than standing most of the year apart from coming out for shows.
Anyway fella, it,s your choice and you,ve got yourself a very clean car there so all the best in whatever you decide.
