You have all proberly been asked this question a million times but so sorry if you all have. Any way i'm not working at the momment really as i have to get major surgery on my wrist.I've still got some funds there and funds coming regulary i'm still living well and have a stable income but i am wanting to turbo my r31 one without blowing my bank balance in case i'm off work for even longer once my surgery is carried out so roughly how much am i looking at ? without blowing da budget.
