Some friends of ours visited and hired a car from 'Advantage' which operates the 'return empty' policy.
It was a VW Polo which has an 'anti syphone' device fitted.... :(
I sat and looked at their paperwork and the full tank charge has 'tax' added..so if they took it back half full I wondered if anyone got a tax rebate....or do they continually carry on taxing the tax....?
They paid 80 euro for the full tank but used less than half so if another hirer had charged 30 euro more for the hire but had a return full policy they would have been better off..... do any of them have a 'return full' policy currently?
