There are no UK model surfs. Surf is only demostic japan model and made only for japan. These are exported new only to US as 4runner. Countries like UK, Australia, SA, Pakistan, which have RHD rule imports used surfs from japan. So if u r interested in a UK model Surf then rest assured 100% that it has been used 1st by japanese and then exported 2 UK, used by british and then has come to Pakistan. 3rd hand
SSR-G is the top grade of Surf, But intercoolers and sunroofs are both optional. even SSRX can have a intercooler or a sunroof and even and SSRG can be without a Sunroof or an intercooler.
Dealer terms such surfs them as "langari" (LAME). funny.
