The Mustang doesnt do it for me ... I did look at the C43 at some point last year , not really looked into C63/s , prolly too shouty for what I need. RCF is a bit of a left field car.
Fair enough, sounds like you want an M2! I just personally don’t think they offer great value anymore, especially not brand new.
Do you need 4 seats? If not you could take a look at sports cars Cayman/Boxster/Supra etc.
