Mercedes-Benz A Class A45.
What to Check Before Buying.
The Mercedes-AMG A45 suits performance enthusiasts seeking supercar-rivalling acceleration in a practical hatchback body, ideal for buyers who want everyday usability without compromising on straight-line speed. This range-topping variant features a turbocharged 2.0-litre four-cylinder engine producing over 350bhp, making it one of the most powerful hot hatches available. The drivetrain delivers exceptional grip through its 4MATIC all-wheel drive system, though the firm suspension can feel harsh on British B-roads and running costs are considerably higher than standard A-Class models. When buying used, check the service history meticulously as these engines demand regular oil changes and premium fuel. Inspect the dual-clutch transmission for smooth operation during slow-speed manoeuvring, as some examples have experienced clutch wear. Listen for any turbocharger whistle or rattles from the engine bay. Verify the condition of the performance brakes and tyres, both of which are expensive to replace. Finally, check for evidence of track use or modifications, as many A45 models have been driven enthusiastically. A comprehensive inspection is essential given the high-performance nature of this variant.
