I'm stuck and I need advice #2 – car

Ok so here's another "I'm stuck and I need advice" post, this post also has a link to University in it (which ones don't?!).

I have the opportunity to buy a 2004 registered Citreon C2 LX. It's in good shape and it's cheap. Insurance is still expensive but I can just about manage because the car's so cheap. Here's the thing though, I'm not sure how much of a necessity a car will be when I move to Cardiff. I would guess it's just as useful in Cardiff as it would be here as I'll have to travel to a hall 40 minutes walk away for kickboxing plus I'll be shopping at Uni.

But do I buy a car, keep it for a few years and build a no claims bonus; or do I keep my money and be a bit more financially secure for when I move to Uni? I think I'm abusing this blog by posting these "help me" questions. I guess I need someone to tell me "yes" or to tell me "no" or I just feel like I'm acting on impulse – which technically I am.

So buy a car or be exceptionally financially safe? Hmm.
