My other option is to talk her out of it and get her to buy a Polo 😀
Obviously I don't know either you or your wife but anyone who is wanting a CS sounds unlikely to settle for a Polo so if you can manage that then perhaps you are the one who can settle the Middle East!
She knows next to nothing about cars, only that some look nicer than others.
I think she is set on a GTI of some sort as long as the colour is nice😀
An oryx white facelift GTI with dsg will probably suit her and if she's happy with that, I won't complain.
That CS was pretty awesome though and I'm no fan of white cars.
