Who Should Buy GMC vs Mercedes-Benz?
If you want the lowest risk and the lowest upkeep, shop GMC. Every tracked GMC model rates good. The Canyon is the strongest, and the 2024 is the pick, while the 2023 is worth skipping for a forward collision system that brakes hard with nothing ahead. For a full-size SUV, the Yukon is the better choice in 2020. Avoid the 2021, and listen for ticking that can signal lifter and camshaft trouble.
If you want the Mercedes badge, stay with the SUVs. The GLB, GLC, and GLE rate good, and the E-Class is the one good sedan. Target a 2022 or 2023 GLB and skip the 2020, which has had blank instrument clusters and spoilers that come off. Check service history for cylinder head and valve problems. Be careful with the CLA, which rates mixed. If you buy one, look for a 2020 and skip the 2022. Check for transmissions that drop into Neutral.
The Bottom Line: GMC or Mercedes-Benz?
For most used-car shoppers, GMC is the safer buy. The Canyon is the strongest single model across both lineups, and a 2024 is the year to look for. Mercedes-Benz costs about $211 more a year to keep running, which is roughly $1,055 over five years. If you still want one, choose a GLB, GLC, or GLE and confirm service records before you pay.
