Mike was very professional and friendly to deal with, on the phone and in person. He supplied the perfect passenger seat to match my existing drivers seat. Very happy with the price, as well as the quality of the product. Highly recommended.
Massive thanks to Mike here at NZKW for helping find the perfect seat and items to go with it to fit my Scirocco. Still yet to put it in but was super helpful throughout the whole process. Definitely recommend coming here for all your needs!
