As I also own a Lupo GTI and an Up, though mines a Mk1 version, I love both cars but for different reasons. The Lupo has the 'grin' factor, its nippy, handles pretty well, rarity factor and its a car I never want to sell. The Up is more practical on a daily basis, better on fuel, cheaper to tax, better equipped, mine has a cd-player and sat nav, it even handles pretty well too, though mine has the factory 'sports' suspension. I am going to hand the Up to my son for his 1st car soon, something I always planned to do anyway, but its ideal for him and safe too. If you park them side-by-side the dimensions are almost identical!
