Yeees... just booked my baby in at Car2Tint in Huntingdon (thanks to garvey and parsco) to get the all the rear passenger door glass and rear windscreen tinted! Not sure how dark I will go, but just got off the phone with them and they said they have 6 shades so shouldn't be a problem.
Getting this done next Wednesday (10th December) so I shall take some photos after it's been done (and after the car has been cleaned!) and upload them...
(Next treat, lowering all around 30mm...)
