Call Holdcroft Honda and ask for club discount, mine was £190 in primer, I sprayed it myself, although I expect a bodyshop would do it for less than £100.
Called Holdcroft Honda today, price including vat was around £430, that includes them painting it aswel. I didn't expect it to be that expensive, I will definitely be asking for a club discount and just in primer when I decide to get one.
