There is no comparison. In 1998 I purchased a Lexus ES300 and for the most part have had no major work done to it other than regular maintenance. Finally had to get the rear seal replaced due to a oil leak problem. At this point there is around 170K mi on the vehicle and its beginning to show wear in handling and engine, but still a very good auto.

2 months ago I purchased a mercedes '91 300E well maintained with 210K mi. Driving this vehicle is simply unbelievable. Although the Lexus has more power and better stock audio, the MB beats it comfort wise and attention hands down. At 210K mi I had it up to 110mi/hr on the interstate and she purred like a kitten. Every day I am simply more amazed how well this auto functions over against the Lexus.

Just wanted to add my 2 cents worth.
