S63 - wheel alignment limited by speed?
Findings: Roads in the Carolinas are very bad. Beyond the obvious potjoles on sides, the surface is wavy with minor ups/downs,
Slight improvement in Virginia and much better in PA with the best being (and I was shocked) New Jersey roads! I thought NJ had poor road quality but after seeing the 4 other states I stand corrected.
Now to the vehicle - at speed just above posted limits, the steering wheel would vibrate/shudder. Even the chassis was being overly responsive with vibrations. This situation improved in PA and NJ but it raised questions regarding alignment since this was a CPO.
Upon calling the selling dealership service manager to inquire about print-out or electronic record of their alignment, was told their equipment only allows balancing and alignment up to speeds of 70mph!
Does that claim make any sense? After all the car does not have a speed limiter at the 70mph mark. Upon further discussion, I was told that driving above 70mph is illegal and the dealership does not support such activities and are not responsible for how the car behaves above the legal limit. But the S63 also has a track mode which allows for much higher speeds - so how is the buyer supposed to avail of that feature?
All in all - not pleased with the service at the selling dealership. I have not explored this further yet at my local dealer who will be servicing the vehicle for the next 3 years (bought a pre-paid manintenance plan).
Any pertinent feedback on above issue is appreciated.
Do an alignment at MB with fresh tires. With straight OEM wheels as befitting.
Problem solved.




BTW, the rims and tires are OEM, AMG 20" wheels and Michelein Pilot Sport 4S tires.

As for alignment, there's no speed limit on alignment. The factory alignment works on the German Autobahn at way higher speeds than you can legally drive here. Bunch of baloney on the selling dealer's part. These cars are designed to rip down the German Autobahn at near 200 mph on a Sunday afternoon while the rear passengers are sipping tea.

When I bought my CPO from Mercedes Benz of Medford in 2022, 3 of the 4 wheels were bent. The car was previously owned by the owner of the dealership so I thought the car was going to be "minty", but it wasn't. It was a beautiful car indide and out, very well maintained. Anything that is promised as reconditioning or even checked on the CPO certificate is a joke. A Mercedes CPO is just a warranty.
