17inchs no problem, just ask them... for tints not sure they might give you contact details for where to go to get them tinted but it's £120 to get the rear tinted. :D
 
They can provide the 17" wheels bit they aren't cheap to buy. It's unlikely they will do the same cost as the factory option.
 
Thanks for the advice.

I ordered the car over a week ago, and its on its way to the dealer apparently, but I got money for my birthday so was thinking of upgrading a couple of accessories. But I think its too much hassle.

Cheers for the replies :)
