A van would be fine... I had sort of thought about a Vanette window van, or a Cabstar double cab (*if* I could find one to fit the budget)... I could then borrow it for carting stuff about! I don't know whether I could swing it for these rather industrial choices!
If the scooter really is that big.
I'll try and get 'em! From the Inner Net, it's an Evolution 8, length 1480mm x width 640 mm, height I don't know.
A trailer has been suggested - possibly a good idea.
Buying another "scooter" to fit in a car boot has been suggested, but these sort of ones don't deal with other than billiard-table terrain too well (+ the person who'll be using the "scooter" is very scared of "tipping up".
