2023 BMW 4 Series 2.0 420i M Sport Auto Euro 6 (s/s) 5dr

The price, mileage, photos, description and feature list are supplied by the seller. Key2Car doesn't own or inspect the cars advertised here, and we don't set the prices.

Some technical details — engine size, fuel type, body style and first registration date — are matched automatically from the registration number. Where a manufacturer offered several versions of the same model, the detail shown may describe the model generally rather than this exact car. Optional extras fitted from new may not appear.

Before you buy, check the details that matter to you against the car itself and its V5C registration document. If something on this page doesn't match the vehicle, tell the seller — and tell us, so we can put it right.

Our running cost figures are estimates built for this specific car, and every one is labelled so you can see how much weight to give it:

• Calculated Worked out from real data about this vehicle where we have it.
• Estimate Based on the type of car it is. Servicing, tyres and insurance fall here. Useful for comparing cars, not a price you've been offered.
• Not available Shown only where there's no sensible basis for a figure. We'd rather show nothing than invent a number.

Insurance is the least predictable of these by a wide margin. Two people can be quoted very different premiums for the same car depending on age, postcode, licence history and insurer. Treat the range as a starting point and get your own quote.

Fuel prices, tax rates, servicing costs and MOT fees all change over time. Key2Car is not a financial adviser and nothing here is a quote or an offer of finance.

MOT status, test history and the mileage readings recorded at each test come from the DVSA where available. We show what the seller has told us, and any status the DVLA/DVSA data confirms.

This is not a full provenance check. It does not tell you whether the car has outstanding finance, has been recorded as stolen, written off, or scrapped, and it does not confirm the number of previous keepers. Those checks are worth buying separately before you hand over money.

Owners, service history and keys are entered by the seller and aren't verified by us. Ask to see the service book and the V5C, and make sure the seller's name and address match it.
