With all the road, wind, engine, transmission and tire noise, why would someone spend that type of money on a car system??? I just don't get it. My friend has Lexus LS430 with levison system in it. It sounds good to me when the car is park in the drive way with the engine off but when the car is on the road it doesn't sound that much different than a reasonablely good system. I rather spend the money on my home system.
