Buying trip to UK

My chin is literally on the floor with the difference in price for roofing materials. I'm tempted to drive to UK and fill my car, but wondered if anyone wants to share costs of the trip. I have a VW Touran and can take all the seats out, so quite roomy.

I will save £500 but the journey costs nearly that! Hence the need for someone else looking to save some money.

Paint, car parts...etc all radically cheaper. I will be returning to the Toulon area. Happy to make detours via most reasonable places.

I'm sure I'm not alone here
