Welcome mate, nice car. I am just up north from you in Newcastle and have a roadster in the rouge red. Had mine for 18 months and absolutely love it. No problems with these cars, although the roof can have some problems just like all convertibles. Plenty of advice though on this excellent forum, there is also a dedicated roadster folder if you haven’t already seen it.
Be sure and join the Official Sydney Fairlady Z Owners club on Facebook, They organise plenty of social runs, mainly 370z, a member also has a cherry red roadster as well - Enjoy
