It was a 100% improvement. Of course the THUNK that I could feel in my feet was gone, but the best improvement was the highspeed tracking. Our roads are just plain bad with potholes waves different types of pavement etc.. When you would hit a wave in the pavement or uneven grade your car would shift over sometimes a half a lane if the wind was helping it out. Out of all of the improvements' the TE got which was basically everything, that was my favorite performance improvement. And you are right on the money with the cost I did have a slightly lower estimate in the 490 range but I went with the MB service to make sure it was done right. Also it really seemed so make the ride a bide queiter because of the reduced vibration. How is school treating you? I wish I could go back those are some goood times!
