I ordered the oversize 19 inch tire, and the adjustable suspension system on this car. I am very satisfied with the tires perfomance and tread life. I rotate every 6500 miles. With the 4-matic, I have been extremely satisfied with this car's handling and perfomance. I am baffled by some of the negative reports written here? Am currently looking at new tires and am considering the LX20 with EccoPlus since it is a new tire and my current 4X4 Contacts. I am an agressive driver but am not a 'brake-rider'.
