Dear Dave,
I'm sure you will love your new RX.
Out of curiosity - why was the VW Treg so disasterous?
Re. your question, you cannot add the power tailgate as it is a factory fit item.
Enjoy your new car.
Cheers, John.

john, car disasterous because VW dont have any real customer service back-up for this car, only selected dealers can service, any problems vw dont want to know. I am well shot of it, nice to look at drives nice but when you got probs they are definately YOUR problems
