The 2020 CLA is the second‑generation compact four‑door coupe and most petrol examples use small turbocharged engines with an automatic gearbox (some models use a dual‑clutch, others an 8‑speed torque converter depending on engine). Many Irish examples wear the AMG Line spec with bigger wheels and firmer suspension — that looks good but raises tyre, wheel and suspension repair costs and can make the ride harsher.

• Automatic gearbox behaviour: ensure smooth, consistent shifts and ask about any gearbox fluid/software service history (DCTs can need specific maintenance).
• Turbo and engine condition: listen for turbo lag/whine, check for smoke on hard acceleration and any signs of oil leaks.
• Wheels, tyres and suspension: inspect low‑profile tyres and alloy rims for kerb damage and check for noisy/shaky suspension components (especially if AMG Line).
• Rear passenger and boot practicality: confirm rear headroom/legroom and check the boot for scuffs or hidden damage under the floor.
