I traded in my car this weekend. I had owned a 2006 430S 4matic for 4 years. In that time it was trouble free for 2 periods of 6 months. Traded it in with 80k which was limited due to the multiple issues that we encountered. First the tire pressure sensors went...3 times. Next the turn signal control stick disintegrated. Next the heated steering wheel control had the same issues. The washer fluid reservoir cracked ($450). I went through a 1/2 dozen bulbs and each time a bulb goes out it disables the electrical system. The ultimate issue was the continued shaking when the car went over 50 MPH. Apparently there is a known issue with the struts, but MB will not own up to it. I almost forgot to include the A/C unit working on and off, usually in the winter. Never again!!!
This vehicle has always been a truly remarkably beutiful and classy sedan, aboive all of its competitors. The only vehicle close to it is its older models. Competitors, like Lexus and Acura and such other Japanese companies cannot touch it. Its luxury is unsurpassed. Mercedes-Benz has been the very best in upscale luxury sedans, and always will be - with the S-Class sedan.
I have owned many luxury vehicles. I would never buy another American luxury car, especially Cadillac. The MB surpasses the Cadillac 1000% in comfort, stability, design, and value in the long run. Find a good MB mechanic vs. the dealer to do the maintenance because the dealers rip you off - like $300 for a oil change!
The ride is velvety smooth and luxurious. I have never driven a car so comfortable, quiet, smooth shifting and excellent. The front and back have a large amount of roominess with all this comfort. It smeels of luxury. It has plenty of power, so when you want to go fast, it'll do it easily. It has 3 driving settings: Comfort, Sport 1 (firm driving) and Sport 2 (more firm driving) which makes it so much more fun.
