This is the first‑generation CLA (C117) era; 2016 models are around the mid‑life of that run and may be facelifted variants with updated trim. Petrol automatics come with Mercedes' 7‑speed auto hardware (some cars use a 7‑speed dual‑clutch variant depending on engine) — both need a clear gearbox service history and DCT mechatronic work can be costly if it fails. Petrol engines are smooth and responsive but won’t match diesel economy for long motorway commuting; optional sport suspension or larger wheels can make the ride firmer.

• Automatic gearbox behaviour: ensure shifts are smooth with no jerks or hesitation; ask for evidence of gearbox oil/mechatronic service for DCT cars.
• Turbo and charge system: check for smoke on hard acceleration and inspect intercooler/hoses for oil leaks or loose clamps.
• Rear seat/boot area for scuffs and water ingress and check underside/boot floor for corrosion where moisture can collect.
• Front suspension bushes and lower control‑arm joints for knocking or uneven tyre wear over bumps.
• Tyre age and condition — on a 10‑year car the manufacture date matters as much as tread depth (replace if tyres are >6 years old).
