Who Should Buy Acura vs Mercedes-Benz?
If you want the lowest hassle and upkeep, lean Acura. The ZDX rates excellent, and the 2024 is the year to buy. Test the brakes hard, because owners report pedals that sink and emergency braking that fires with nothing ahead. The RDX, TLX and MDX all rate good. On the Integra, pick the 2024, skip the 2023, and watch for a steering wheel that sticks at highway speed and then lets go.
If you want a luxury badge, lean Mercedes-Benz, but stay with its SUVs. The GLB, GLC and GLE rate good, and so does the E-Class sedan. For the GLB, target 2022 or 2023, skip 2020, and ask for service history because some owners report cylinder head and valve failures. Be cautious with the C-Class, A-Class, EQS and CLA, which all rate mixed. If you still want a CLA, the 2020 is the pick and the 2022 is the one to skip. Watch for transmissions that drop into Neutral on that model.
The Bottom Line: Acura or Mercedes-Benz?
For most used-car shoppers, Acura is the safer buy. The ZDX is the strongest model across both lineups, though only two model years exist and the 2024 is the one to get. Choose Mercedes-Benz only if you want its luxury feel and will stick to the GLB, GLC, GLE or E-Class. Budget about $281 more a year for upkeep, roughly $1,405 over five years.
