To buy or not to buy

Fuji Finepix S6500fd

I'm thinking of buying this camera that a friend's mother is selling. I don't know that much about cameras. So could anyone tell me wether I'm doing good in buying this one? I'm not certain wether I should buy it because I'm hugely intrested in photography. But I might become if I have it! I'd like to take better photos then with my old camera. Then I'd be able to post outfit posts ;)

In July I'm going to participate in the Elite Model Contest. It was a completely spontanous decision, I don't think I have any real chances to get through. But it's a great experience and it's gonna be fun :) I'm going there with Steffi. Visit her blog! :)
