First I have to correct a mistake, the car is a B T6, not a T5.
I plan to use STP Black Gold insulation material under the carpets.
Anybody done such that could send me some hints?
The ear plugs is not an option, I plan to travel with this car and my wife.
About interior, as I'm in Europe, not much sense to buy this from the US.
Any experience there with these, or could you recommend some?
