for a 2001 and a 1.2 8v (?, an ELX JTD WOULD be well worth it) £600 is about right,
you'll have to replace:-0
bonnet,
right wing,
left wing may straighten
bumper
slam panel (often hard to find a good one, AND they are glued in so have to be new or welded back in )
pair of lights and brackets.
maybe the front part of undertray thing
I'd say if you could find a stolen recoved or rear ended black mk2 then maybe you could do it all for £200-£250?
was it recorded on insurance as being crashed then written off or something? if it was then your premium would maybe be higher than a normal car (insurance co's are anal) and its resale will be affected
