The INFINITI M (2010-13) 4DR SALOON 3.7 V6 320 EU5 S PREMIUM AUTO7 is a premium four-door saloon, offering comfort and performance rather than the practicality of an SUV or hatchback. In the UK, it is an uncommon alternative to favourites such as the BMW 5 Series and Mercedes-Benz E-Class. Its 3.7-litre V6 and automatic gearbox give it smooth, confident progress and a more engaging feel than comfort-focused rivals. The spacious cabin and equipment suit long-distance commuters, couples and families who want a refined, distinctive daily car. It is less suited to buyers prioritising low fuel bills or city parking.
