I’m a bit suspicious that this is a wind-up… very strange questions being asked
And to say that the furthest you’ll travel is 30 miles but not an EV cause they have low range is just odd

Anyway, just in case it’s a serious question 
go onto the Motability Web site, search for all the cars suitable for under 25’s, write them down along with the prices, cross off the ones you’re not interested in, then start going around the garages to try them out… no one, here or anywhere else, can decide which is the best car for you. Good luck in your search 
Come to think about it, you could be right, as didn’t twig on the EV bit!
