Don't know about recommending a specific car, Naomi, but you/your friend might find this best in category list from What Car useful.
From the sound of things, cars in the "city car" or "supermini" or "small family saloon" class might suit your friend the best, and I am pretty sure you can arrange a good finance deal on a new car with any major brand.
Oh, there is an annoying video link top right hand corner that plays on the first page - sorry about that ;)
