2025 Mercedes-Benz EQA 300 AMG Line Premium + 4M Electric · FV25 AOR

Running an electric EQA 300 is notably cheaper day-to-day than running a comparable petrol or diesel SUV, but the purchase price remains premium. Real-world range for the EQA 300 4MATIC is typically around 240-260 miles in mixed driving, with efficiency around 3.0-3.5 mi/kWh, meaning home charging costs on a standard tariff of around 25p/kWh work out at roughly 7-8p per mile, or £14-£16 for a full charge from empty. On an off-peak tariff such as Octopus Go or Intelligent, this can drop to around 3-4p per mile. Public rapid DC charging is more expensive, typically 50-70p/kWh, so habitual rapid charging noticeably raises running costs.

Road tax (VED) is currently free for fully electric vehicles, though a small charge may apply from 2025 onwards depending on the list price band — confirm current rates. Insurance for an EQA is in a relatively high group (around group 38-40 for this trim), so expect premiums of £600-£900 per year for a typical driver. Tyres are a notable cost: the AMG Line Premium + specification uses large-diameter alloys (typically 19 or 20 inch) with low-profile tyres that can cost £200-£350 each, so budget accordingly. Mercedes-Benz servicing is required every 12 months or 12,500 miles, and although EVs have fewer consumables, expect to budget around £300-£500 per service at a main dealer, or less at a specialist.

Begin with a thorough inspection of the exterior panelwork for parking damage, particularly to the larger alloy wheels and the black painted bumpers, which show stone chips and scuffs more readily than lighter colours. Inspect all four wheels for kerbing damage and check that the tyre brands and tread depths are consistent across each axle — uneven wear on a near-new car can suggest tracking issues or accident damage. Examine the charging port door for proper operation and the rubber seal for damage, as moisture ingress here can cause warning lights. Check the underside (or use a ramp/dealer lift) for any signs of damage from kerbing or speed humps, particularly given the EQA's relatively low ride height in AMG Line spec.

Inside, test all electrical systems methodically: both keyless entry and start functions, the MBUX infotainment system responsiveness, satellite navigation operation, climate control (including any pre-conditioning features), heated seats, electric tailgate, and the reversing camera and parking sensors. For the battery and drivetrain, request a dealer-level diagnostic to confirm no stored fault codes, current State of Health, and whether the high-voltage battery has any degradation or cell imbalance. Verify the charging works on both AC (home wallbox) and DC rapid charging, and check the charging cables for any damage to the plugs or cables. Finally, confirm the build date on the VIN plate matches the registration date and that the service book (digital or physical) is present and stamped up to date.
