Most 2023 petrol automatics in the 2 Series are turbocharged petrol engines with an automatic gearbox tuned for smooth shifts; economy won’t match a diesel or hybrid but performance is responsive. This model is commonly the 4‑door Gran Coupé (hatchback tail) rather than a traditional saloon, so boot access is practical; check whether it's the smaller 218i (lower output) or a 220i/M‑Sport variant as that changes performance, economy and insurance.

• Automatic gearbox behaviour: no jerking, smooth up/down shifts and no hesitation on acceleration — check for any transmission shudder or delay during low‑speed manoeuvres.
• Turbo/boost system: listen for unusual turbo noise under load and check for oily smoke or strong oil smell on start/accel (early signs of charge or turbo oil issues).
• Suspension and steering: test over bumps for knocks or clunks, and inspect for uneven tyre wear (M Sport setups can cause inner-edge wear).
• Electrics and driver‑assist kit: confirm reversing camera, parking sensors, lane‑assist and adaptive features operate correctly — repairs can be costly on high‑spec cars.
• Rear hatch and seat function: ensure tailgate struts are firm, rear seats fold cleanly and boot seal is watertight (the Gran Coupé hatch can show wear around the tailgate seal).
