One aggravating trait of an earlier model E420, was a slight delay on kickdown when hitting the throttle at higher speeds. This very slight hesitation is still evident in the 1999 model. The sedan is so planted to the road at high speeds you can understand how people can achieve triple digit speeds for long distances on the limit-less German autobahn. The interior is the epitome of automobile quiet with road, wind and tire noise virtually eliminated. The dashboard layout is attractive but fairly straight forward for a sedan in this class.
Instrumentation is easy to read and the swtichgear is right at hand.
However, be forewarned that using the stereo system is virtually impossible without consulting the owner's manual. Once familiarized with the intricacies of the system, it is easy to use. And speaking of stereos, the E Class has one of the best in the business. My only gripe with the switchgear is that the turn signal stalk and the cruise control stalk, both on the left side of the steering wheel, are too close together. It takes a couple days behind the wheel to eliminate accidentally hitting the cruise control while signaling a turn.
