 Test drove many luxury vehicles before deciding on the E350. Great offerings from other manufacturers. Electronics not as reliable as Japanese models, but only BMW felt as solid and refined. By far the best E-class to date. Very smooth with very little noise intrusion. Good accelleration, solid handling & strong, consistent braking.  Relatively conservative styling, but still an attention magnet. The no-cost Sport pkg gives the styling a bit more edge, but still classy.  Navigation isn't 3D and you can't type in the name or # of a business you wish to travel to, but otherwise, no complaints. Harmon Kardon sound system is great for most listeners and is far beyond earlier Bose systems.
