About the 2018 Mercedes-Benz G-Class

The 2018 Mercedes-Benz G-Class is a suv that earns a Carivo score of 6.8/10 — rated Good. Its strongest dimension is Technology at 8.9/10, while Reliability at 6.7/10 is where it trails the competition most noticeably. It's a capable but unexceptional suv — 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. At 6.7/10 for reliability, this suv trails its segment. That doesn't rule it out, but go in with eyes open on running costs. Safety lands at 8.0/10 — solid, though some rivals offer more advanced driver-assist features as standard. Confirm official results for your trim at nhtsa.gov/ratings.

Performance at 6.8/10 is a genuine liability and a score that should factor heavily into any buying decision. The powertrain and chassis dynamics trail class rivals by a meaningful margin — don't overlook it. On technology it rates 8.9/10: a modern, well-integrated suite that compares favorably with anything at this price point.

Priced from $119,269–$157,311, 10 MPG, seating 5, the Mercedes-Benz G-Class sits in the luxury tier of the suv market. At 7.0/10 for value, it delivers fair pricing for what's on offer, though the best alternatives in this price range score slightly higher. 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.

Verdict: The 2018 Mercedes-Benz G-Class sits in the middle of the field. Until its performance and reliability scores improve, stronger options exist at this price. Worth a look if it fits a specific need; otherwise use our compare tool against the segment leaders first.
