I priced out the factory air suspension for a Touareg and it came to 2200.00 plus labor and misc. parts . I can only guess it would cost about 1500.00 labor to install. Or about a day and a half labor. So I guess the question would be is it worth around 4000.00 to have adjustable air ride and would it be smother on the hwy. Also has anyone looked into this.
