The ALFA ROMEO 166 (1999-05) 4DR SALOON 2.5 V6 24V SPORTRONIC AUTO4 is a large, four-door executive saloon, rather than a hatchback or family SUV. It was Alfa Romeo’s alternative to established premium cars such as the BMW 5 Series and Mercedes-Benz E-Class, offering Italian styling and character. The 2.5-litre V6 and automatic gearbox suit relaxed journeys and drivers who value smooth performance and an individual choice. Its roomy cabin can suit couples or small families, though age and running costs make careful checks important; it is less suited to budget-focused first-time drivers. The mycarcheck.com sample is small: 10 look-ups covered five distinct VINs, so figures are indicative, not a full-market picture. Checks show an average recorded mileage of 100,000 and 5.2 previous keepers; average annual mileage was 2,000. The average private-sale valuation was £300, making condition, history and a thorough inspection especially important when considering this rare, ageing Alfa.
