There is a section in the PCP contract about this subject. Cannot remember the detail but Audi finance details the maximum amount of time / days of which a car is allowed to be outside of the UK. I think it's a total of 60 days in a year. Also just found this which applies to road trips / driving holidays:
If you have a Contract Hirefinance agreement with us and wish to take your vehicle abroad, you will need to get a VE103 Foreign Travel Authority certificate from us. If you are planning on travelling abroad, please ensure that you have adequate insurance cover.
Simply complete the form below and your VE103 Foreign Travel Authority certificate will be sent to you within 14 days of your request.
Please note this is valid for one year only and allows travel for up to 60 days in Europe.
