Quick Buyer Checklist for the X166
Buying a used Mercedes X166? Check the extras before you pay for them.
Many used cars are advertised with premium packages that aren't factory original or omit major equipment gaps. Don't just take the seller's word for it.
Why check the factory data
The X166 generation introduced complex electronic architectures and high-value optional packages that are frequently misadvertised by dealers and private sellers. As a buyer, the only way to guarantee what you're buying is through the original factory option codes and equipment.
Originally named the GL-Class, the X166 was facelifted to the GLS in 2016. It offers dynamic driving modes and three complete rows of passenger luxury.
