The ALFA ROMEO 166 (1999-05) is a large executive saloon, a distinctive alternative to premium cars such as the BMW 5 Series and Mercedes-Benz E-Class. It occupies a specialist corner of the UK used-car market: comfortable and spacious, but now an uncommon older choice rather than a mainstream family saloon. mycarcheck.com has recorded 166 checks covering 91 different VINs, a useful snapshot of a low-volume model in Britain. The average private-sale valuation is £500, while checked cars average 104,000 miles and around 3,000 miles a year. They have had an average of just over four previous keepers, suggesting many are now occasional-use or enthusiast-owned cars; these figures describe checked vehicles, not every 166. Its elegant Italian styling, relaxed long-distance comfort and engaging feel set it apart from more commonplace executive saloons. Best suited to enthusiasts or experienced buyers seeking character and space, it rewards careful inspection and a thorough history check.
