Hi i was wondering if anybody else has experienced what is probably a major design flaw? At 70 - 100 kms/h put down 1 rear window 3/4 to all the way down. Ive had a little of this buffetting before in cars with sunroofs but never like this, it caused my passangers headaches almost straight away and myself i could almost feel my head pulsing! It probably wont bother me again now i know of it, and 99% of the time its just my partner and myself. Also the climate control is enough to keep me happy any way i just wanted to bring it up and get some other opinions.
