Hi,
Depends on the colour. Have just had a car resprayed for a friend. Cost £1200 to prep and paint a scooby estate. Candy red with a ColourShift clear top coat, He did under bonnet, door shuts and boot etc. The final product looked stunning.
I was quoted between £500-£800 depending on colour. I know the lad so he will do a deal for me. Had some of the light blue Alfa colour that flips, said he would put thay on the golf for £400 inc all shuts, bonnet etc. Only because the previous job had left paint spare. Dont have £400 spare at moment.
As mentioned by somebody further up, it depends on how much prep time needs to be put in. If you want every panel to look like a mirror it will be long and expensive. But a blow over will be a waste of money and dull.
