You're best printing out all the equipment sections of the website for the Polo - the links are the small ones on the right hand side after you've selected a car model. It lists every option, which car has them as standard and how much they cost to add - there's about 3 sections - interior/exterior and safety as I recall. Worth a look.
I'm also making the move to diesel (currently driving a Polo 1.6 16v GTi) because of the lower running costs - mpg seems amazing, insurance is generally cheaper and servicing should be too. Lower depreciation on a diesel too.
So i'd go for the 1.4 TDi Sport
