IMO AntNeeUK I would scrap it and get an S3!! hehe!!
No, I would keep at it, as its in good nick, and you would be wasting the cash you have already spent. As a late friend of Pumapeople said, you should buy on condition, not milage! Just look at Vlad on 69,000, and he's more mint that ones I've seen on 20k. After my hi-res pic though, you should get new nuts! Oh, and new ones for the wheels too! hahaha!
Get the wheels done at Lepsons too!
