Why is my BMW 6 Series shaking at high speeds?

I recently purchased a BMW 6 Series and have noticed that it shakes at high speeds. It's a bit concerning and I want to make sure it's not a major issue. Any ideas on what could be causing this?

It sounds like your car may have worn out suspension components, such as the shocks or struts. These are key parts that help to keep your car stable at high speeds. I would recommend taking your car to a trusted mechanic for an inspection and potential replacements if needed.

Another possible cause could be misaligned wheels. This can cause your car to vibrate and shake at high speeds. I suggest taking your car to a tire shop to have the alignment checked and corrected if necessary.

It could also be an issue with the tires themselves. Make sure they are properly inflated and have enough tread. If they are worn out or the wrong size, this can also cause shaking at high speeds.
