As the name suggests its, as far as I can see, little more than a styling package. £2345 more than the EX. On paper.
But metallic paint is standard, saving either £550 or £750 of the price difference, and nicer wheels which are a £760 option on the EX.
Plus a few other styling changes that might be a £860 option on the EX. (or do they only come by adding the £1550 style plus pack ?)
Might be cost effective for those who would otherwise order the same bells and whistles. Otherwise ......
I notice the SR mentions a tilting wing mirror to aid parking. (down to kerb?) Thats new I think.
