Window tints

Hi all I'm going to get the back windows tinted as I don't have a parcel shelf and also have the dog in the boot so would mean keep removing it.Ive got a quote back and also can get the passenger ones done for another £20 but don't want to go over the legal limit.someone told me the fronts already have a slight tint on the freelander so any tint would put it over the limit.any advice?cheers

i have 100% on all back windows and 30% on front thats the legal limit

The driver's and passenger's window must let 70% of light through. Once you go behind the driver's door you can do what you like. After all it's no different than driving a van.
