Just to bake turd a little a longer here, but I've 100% seen more GT86's on the UK roads than I have 370Z's.
About 3/1 easy I'd say.
I have to say that I see way more 86's than 370's in Bournemouth, in fact I see more Porsche's and Ferrari's in Bournemouth than 370's, cant even remember the last time I saw a 370's driving along.
Same around guildford! Way more amg's too.
