I did ask permission and got an email reply saying yes…..
Thank you for your email dated 17 February 2020 enquiring about having privacy glass added to your Mini Countryman. I have just spoken to your husband regarding the possibility of having a tinted film fitted to your Motability car. However as you are our customer I need to confirm the process with you aswell, I do hope you find the following information useful.
It may be helpful to know that whilst we would be happy for you to have privacy glass fitted to your car, this would be in the form of tinted film that would be applied to the back windows. All we would ask is that a reputable company is used to fit the film and you cover any costs involved. This can be fitted at your convenience.
