Mercedes CLA plug‑in models are usually sold as the '250e' style PHEV and combine a petrol engine with a traction battery and electric motor; the electric-only range depends on battery size and spec but expect real‑world around 25–60 km depending on trim and conditions. As a 2025 example the vehicle will still carry manufacturer warranty on the high‑voltage battery — confirm remaining warranty length, that the charging cable(s) are present, and whether any software/firmware updates have been applied that affect EV mode or gearbox behaviour.

• Hybrid battery state‑of‑health report: confirm current usable electric range and battery warranty coverage.
• Charging equipment and inlet: that the Type 2/Mode 3 cable (and any adaptor) is present, the socket seals clean, and the car charges correctly at home/public points.
• Automatic gearbox behaviour: check for smooth shifts and no hesitation while accelerating from low speed (some PHEV software updates improve shift maps).
• Brake feel and regenerative braking: ensure the car recovers energy predictably and there is no judder or excessive pad wear from city regen use.
• Tyres and ride: inspect tyre condition and sidewalls (many CLAs run low‑profile or run‑flat tyres) and check rear seat headroom/boot access to be sure it meets your family needs.
