Mercedes Benz CLS Class for sale

C class will be more reliable in general and cheaper to repair/maintain. CLS is based on the E class, larger engine, air suspension, etc (more things to go wrong, more expensive if they do). A C300 of any year is a 2.0 turbo 4 cylinder, generally pretty reliable.

The CLS often comes equipped with Mercedes’ 7G-Tronic automatic transmission, which is generally reliable but can develop issues over time. Owners report problems including rough shifting, delayed engagement, valve body failure, and speed sensor problems on the seven-speed auto in petrol and diesel variations.

Neither the Mercedes-Benz A-Class nor C-Class is inherently “better” —they serve different needs: the A-Class is a smaller, more affordable, efficient starter luxury car, great for city driving, while the C-Class is a larger, more spacious, powerful, and luxurious executive car, better for families or long commutes. The C-Class offers more advanced tech, comfort, and powerful engine options, whereas the A-Class provides excellent value, agility, and tech like MBUX at a lower price point.

While the pricier CLS does come with more standard features like the FrontBass System and heated front seats, even the CLA delivers luxuries like the 14-way power front seats with memory, dual-zone automatic climate control, and a central controller and 8-inch color display.

You should generally avoid older Mercedes models known for complex electronics and air suspension, particularly the 2007-2013 S-Class (W221), 2006-2011 ML-Class, 2012-2018 CLS, early 2015 C-Class (C300), and certain GLE/GLS (around 2016-2020) due to issues like timing chain stretch, air suspension failures, electrical gremlins, and overall high repair costs, making them costly financial risks on the used market.
