About the 2018 Mercedes-Benz CLS

Our scoring places the 2018 Mercedes-Benz CLS at 7.2/10 overall, which translates to a Good rating for this sedan. Its strongest dimension is Technology at 8.9/10, while Value at 6.3/10 is where it trails the competition most noticeably. It's a capable but unexceptional sedan — stronger alternatives exist if you're willing to shop the segment carefully.

Reliability and safety are the two dimensions that matter most for long-term ownership costs. Reliability is the weak spot: 6.3/10, under the class average. Review the recall record on this page and price in extra maintenance headroom. The safety score of 8.1/10 is solid mid-pack territory. If advanced driver aids matter to you, compare standard equipment carefully and verify ratings at nhtsa.gov.

Performance scores 7.1/10 — competent for everyday use. Acceleration and handling are adequate for commuting and highway driving, though enthusiasts will want to look at higher-rated alternatives. The cabin tech earns 8.9/10 — infotainment, smartphone integration, and driver-assistance are all close to the best this class offers.

Priced from $64,370–$77,645, 19 MPG, seating 5, the Mercedes-Benz CLS sits in the premium tier of the sedan category. The value score of 6.3/10 is a red flag — comparable alternatives offer meaningfully more for the same outlay. Shop the segment before deciding. At 8 years old, resale value, parts availability, and whether a successor model has improved on its weak points are all worth investigating before committing.

Our take: The 2018 Mercedes-Benz CLS is a passable sedan but not a standout one. Weaknesses in reliability and value hold it back from being a strong recommendation. It may suit buyers with specific needs it serves well, but we'd encourage comparing at least two or three higher-scored alternatives before deciding.
