No, no and thrice no. Essentially it is their high margin upsell so unless maximum convenience is your prime concern, avoid it like the plague. @Teckno from Melbourne had a "new car paint protection" done by an accredited professional detailer and the results were simply stunning! I would go even further and get the dealer to transfer or have the car collected straight off the transporter still in its transport wax and plastic panel protection to your detailer prior to your official collection. This is a service arranged by many dealers of high end marques here in the UK. Under no circumstance should you allow the apprentice workshop monkey anywhere near your virgin paint if you value the quality of the finish.
