The ALFA ROMEO 166 (1999-05) 4DR SALOON 2.5 V6 24V LUSSO is a large, four-door executive saloon, aimed at buyers wanting something more distinctive than an everyday family hatchback. In the UK used-car market, it sits among older premium rivals such as the BMW 5 Series and Mercedes-Benz E-Class, but offers Italian style and character. The 2.5-litre V6 gives the 166 a smooth, engaging feel, while Lusso trim brings a more comfortable, well-appointed cabin. It is best suited to enthusiasts, couples or small families who value relaxed motorway journeys, roomy saloon practicality and a car with presence; running costs and age-related upkeep matter more than outright economy. Compared with German alternatives, its appeal is its expressive design and distinctive driving character. Mycarcheck.com’s two checks covered two VINs, so figures are limited: average mileage was 154,000, annual mileage 8,000, two previous keepers and a £200 average private-sale valuation for this car.
