In whose opinion, for what purpose, budget, blah blah blah.
Very ambiguous question dude.
I dont know anything bout coronas anyway... Other than the QLD dept of trans registerd my Mark II as a corona???
Go figure
By mark two you mean MX23????? in which case that is a corona. Otherwise i'm stumped. The best bolt in is simply the 3tgte, but i don't know how often corona TT142 half cuts are actually available.
