My '96 GLX has so much interior noise, it's driving me nuts. What can be done about this? Do the GLX's with leather inherently have more interior noise than those with cloth interiors? Literally every time I drive it I look at the two rear doors to see if they are correctly closed. My A4 honestly has ~50%+ less interior noise and it has ZR rated tires. Help, what's the list's take on this Thanks Vince
