Our Verdict
This 2017 BMW 420 in grey is a sensible used buy, supported by five consecutive clean MOT passes and mileage well below the model average. Buyers should still budget for typical BMW 4 Series running costs and inspect the usual weak areas common to this generation.
Given the spotless MOT record, the main areas to focus on when viewing are not regulatory items but the broader mechanical and cosmetic condition typical of a 2017-vintage 4 Series. Check that all electrical systems, infotainment, and driver-assistance features function correctly, as repairs on these can be expensive on BMWs of this era. Inspect the alloy wheels closely for kerbing damage and verify that the tyre brand and size are consistent across axles, as tyre-related issues are the single most common MOT failure reason for the BMW 420 model overall.
Ask to see any service records and confirm the car has been serviced at sensible intervals appropriate for a petrol BMW of this age. Even though the MOT record is clean, MOT testing does not cover items like brake fluid, coolant condition, or internal engine wear, so these should be verified separately. A pre-purchase inspection by a BMW specialist or a main inspection is well worth the cost given the car's premium positioning.
The 2.0-litre petrol BMW 420 typically returns in the region of 40-45 mpg on a combined cycle, depending on driving style and gearbox choice. Road tax falls into a reasonable bracket for a 2.0-litre petrol of this age, though exact VED will depend on the specific RDE2 compliance status. Insurance is likely to sit in groups 30-38, so quotes should be obtained before purchase, particularly for younger drivers.
Servicing and maintenance tend to be the largest cost area on these cars, with major items such as brake discs, tyres, and air-con regas adding up quickly if due. Realistically, owners should budget for a higher-than-average annual maintenance spend compared with mainstream brands.
Because every MOT pass on GUI105 has been free of advisories, there is no specific defect pattern to chase from the history. Instead, focus inspection effort on the areas that statistically trouble the BMW 420 model: tyres (the most common MOT failure reason across 66,153 examples analysed), registration plate condition and lighting, and the road wheel fixings. On the test itself, check for uneven wear, particularly on the rear tyres which can wear prematurely on rear-wheel-drive 4 Series models.
Beyond MOT items, inspect the engine bay for signs of oil leaks from the valve cover gasket and oil filter housing, which are known weak points on the B48 2.0-litre petrol unit. Check that the auto or manual gearbox selects cleanly, and look underneath for any signs of corrosion on suspension components given the car is approaching nine years old. Finally, verify all dashboard warning lights clear on start-up and that the iDrive system operates without fault.
GUI105 is a December 2017 BMW 420 with the 2.0-litre petrol engine, finished in grey, and has covered 39,307 miles across five recorded MOT tests. Every test since 2022 has been passed with no advisories or defects recorded, which is a notably clean record for a car now nearly nine years old. Annual mileage works out at roughly 4,700 miles per year, substantially lower than the 8,846-mile model average, suggesting light-to-moderate use.
Across 66,153 BMW 420 examples analysed, the model posts an 87.5% MOT pass rate, with tyre condition, registration plate issues, and road wheel fixings the leading failure reasons.
