Hi @Lucio ,i see what you're saying and i agree with you completely. I think if you want to match the vw glass in the rear quarters and for them to look exactly the same then the rears need to be cut out. If you definitely want to fit dummy windows and for them to match the existing ones,then i think you would have to tint the existing windows to match because obviously as you have said,you can see through the existing windows and are never going to be able to see through the dummies
