The PROTON IMPIAN (2001-09) 4DR SALOON 1.6 X is a straightforward four-door family saloon from Malaysian maker Proton, aimed at buyers wanting practical space at modest cost. In the UK it is now an older, uncommon alternative to familiar saloons such as the Ford Focus or Vauxhall Astra. Mycarcheck.com has recorded 12 checks covering 11 distinct VINs, so these figures offer a small snapshot rather than a broad reliability verdict. Across those checks, the average private-sale valuation was £600, recorded mileage averaged 103,000 miles, and annual use averaged 6,000 miles. Cars had around 3.7 previous keepers on average. The 1.6 X can suit commuters, first-time owners and small households needing affordable everyday transport, with a separate boot and saloon layout. Its appeal is straightforward value, though age makes condition and maintenance important. Rarer than mainstream rivals, the Impian offers a less familiar alternative; check its history and condition before buying.
