I still drive my first car. 1998 Ford Ka, a good 150k on the clock, brake problems, tyre problems, air intake problems, been bent round a telegraph pole, on about its third exhaust pipe... would probably buy me something like half the headlamp of that monstrosity up there.
Of course it's too much. You live in London, for heaven's sake - how are you going to pay for ANYTHING else if the car already costs you £6-9k?
Some people astound me. You're a girl, as well, you don't need to have a car and look all impressive. Spend your savings on having a good time in London, where the cost of a pint approaches £5. I came to uni with £4,000 and what with one thing and another that's halved now; all I've got to show for it is a skiing holiday and a few pots and pans. I haven't even gone all out on the drinks.
