benni if your doing a insurance job you want the most expensive paint and all new materials. if its a decent job with some older materials and newspaper instead of proper masking paper and cheeper paint you can do it for about 60 quid if your doing it yourself.
i have a mate who buys cars needing paint in colours he already has the paint for thus its a very cheep job with just a bit of masking tape/paper/bog (filler)/primer/basecoat and laquer
