This is the W176-generation A‑Class (pre‑2018 facelift line) where petrols are usually turbocharged small‑capacity engines paired to an automatic that can be either a torque‑converter box or a 7‑speed dual‑clutch depending on the exact engine. The dual‑clutch versions can show low‑speed jerking or mechatronic faults if not serviced; dealers/previous owners sometimes skip gearbox fluid/soft‑wear items which are costly to fix. Expect typical Mercedes options (infotainment, cameras, leather) that add comfort but raise repair bills if they fail.

• Test drive at low speeds and during city stop/start to check for gearbox shudder, hesitation or rough engagement; ask for any transmission service history (fluid/mechatronic service).
• Watch for excessive oil consumption or blue smoke on hard acceleration — small turbo petrols can show turbo/oil‑consumption issues if maintenance was neglected.
• Verify all electronics: infotainment/COMAND unit, reversing camera, parking sensors and steering‑wheel controls — repairs are expensive on premium models.
• Inspect suspension and subframe areas for wear and creaks on rough roads and look for any corrosion or damage around wheelarches and lower sills (age‑appropriate corrosion can appear after ~9 years).
