A W176 A45 makes sense if you want a compact all-weather performance car and can verify its service and tuning history. Choose a clean standard or well-documented modified example and test both the gearbox and rear-drive operation before paying.
Which Mercedes-AMG A45 W176 should you buy?
The earlier W176 A45 was rated at 360 PS and the facelift at 381 PS. The period facelift road test covers the update. This generation uses the M133, seven-speed dual-clutch transmission and 4MATIC. Verify the actual build and compare separately with the newer W177 A45 S.

Common problems and inspection points
Cooling and tuning
Start cold, check coolant, inspect the cooling stack and look for staining or repeated top-ups. Drive fully warm and investigate persistent noise, hesitation or faults. Ask who supplied any engine or gearbox calibration and verify fuel requirements and insurance.
DCT and 4MATIC
Try cold engagement and warm low-speed shifts and parking. Get repeatable shunting or delay investigated. Request separate transmission and AWD records, check tyre size and circumference, and inspect driveline hardware and seals on a lift.
Brakes, wheels and body
Inspect inner disc faces and tyre shoulders. Test drive modes and adaptive damping where fitted. Check wheel damage, jacking points, lower bumper and boot for evidence of repair or water. Try all electronic equipment and both keys.
Maintenance and parts
The M133 uses a timing chain and separate accessory drive. Confirm oil approval, actual gearbox and rear-drive hardware, and brake equipment by VIN.
