2025 Mercedes-Benz AMG GT 63 Premium + 4MATIC+ A Petrol · RX25 WYM

As of September 2026, this 2025 Mercedes-Benz AMG GT 63 Premium Plus 4MATIC+ falls outside the statutory MOT testing window, which commences three years from the date of first registration for passenger vehicles. Consequently, there are no recorded DVSA test outcomes, advisories, or failure points to evaluate. While the absence of MOT history is entirely expected for a vehicle of this age and premium positioning, it also means there is no independent verification of its roadworthiness from the Driver and Vehicle Standards Agency. The prospective buyer must therefore rely entirely on the supplying franchised dealer or independent specialist for a comprehensive pre-purchase inspection, as the manufacturer warranty and servicing history will be the primary indicators of mechanical integrity rather than governmental test records. Given the high-performance nature of the AMG GT 63 and its sophisticated all-wheel-drive drivetrain, any lapse in the official Mercedes-Benz service schedule should be treated as a significant risk. Without a verifiable MOT trail, it is impossible to establish whether the maintenance trend is stable, worsening, or improving; a clean pre-delivery inspection and complete service book documentation are non-negotiable for this vehicle. The recorded mileage is not disclosed in the available data, which prevents any meaningful comparison against the one-year-plus vehicle age. A typical first-year mileage for a luxury performance vehicle of this calibre generally falls between 5,000 and 12,000 miles, though this can vary considerably depending on whether the car has been used primarily for long-distance touring, urban commuting, or as a secondary leisure vehicle. Because there is insufficient data to confirm whether the mileage is consistent with the registration date, the buyer should request a current mileage reading and cross-reference it with the service book stamps and any available digital service records from Mercedes-Benz. If the mileage is exceptionally low, attention should be directed towards age-related degradation issues such as brake disc corrosion and potential caliper seizure from standing. If the mileage is disproportionately high, a more rigorous inspection of the drivetrain components, including the twin-turbo V8 and 4MATIC+ system, would be warranted to check for premature wear. For a nearly new Mercedes-Benz AMG GT 63 of this age, the inspection priorities shift towards time-sensitive degradation rather than wear from excessive use. Even with low mileage, the 12V auxiliary battery and any high-voltage hybrid system batteries can suffer reduced capacity or complete failure due to calendar ageing, particularly if the vehicle has been left standing for extended periods. Tyres should be examined closely for sidewall perishing and cracking, as the high-performance rubber compounds and staggered fitment on AMG vehicles can degrade chemically over time even if the tread depth remains nominal. Brake discs, often composite or drilled on this model, are particularly susceptible to surface corrosion when stationary in damp UK conditions, which can lead to juddering under braking. During a test drive, the buyer should listen carefully for any suspension clonks from the multi-link front and rear axles, monitor the transmission for hesitant or rough gearchanges characteristic of the MCT gearbox, and verify that the 4MATIC+ system engages smoothly without any driveline vibration. Any warning messages on the MBUX infotainment system or driver assistance anomalies should be recorded and investigated. Fluid servicing on this model is predominantly time-based rather than mileage-dependent, making it a critical inspection point regardless of the recorded odometer reading. Engine oil, transmission fluid, and the all-wheel-drive system oil will degrade through chemical breakdown and moisture absorption over the intervening months, potentially compromising their protective properties. The buyer should request documentary evidence confirming that all manufacturer-recommended services, including the brake fluid change which is typically required biennially on Mercedes-Benz vehicles, have been completed on schedule. A physical inspection underneath the vehicle on a ramp is highly recommended to check for any oil seepage from the engine, transmission, or differential, as well as to assess the condition of the undertrays and exhaust mounting rubbers which can perish. Given the absence of MOT data, the single most important action for any prospective purchaser is to commission an independent pre-purchase inspection from a Mercedes-Benz specialist or approved AMG service centre, ensuring full transparency regarding the vehicle's current mechanical state and validating the completeness of its official service history.
