The HYUNDAI SONATA (2005-09) 4DR SALOON 2.0 139 CDX AUTO4 is a roomy four-door family saloon, not a hatchback or SUV. In the UK, this uncommon model offers a value-focused alternative to the Ford Mondeo, Vauxhall Vectra and Toyota Avensis, with straightforward transport and the convenience of an automatic gearbox. Mycarcheck.com records are based on 19 look-ups covering 11 distinct VINs, so they provide a snapshot rather than a full market survey. Across these checks, average recorded mileage was 76,000 miles, with annual use around 5,000 miles; cars had about three to four previous keepers. Average private-sale valuation was £1,000. The 2.0-litre petrol engine and automatic gearbox suit commuting and longer trips, while the cabin works well for couples or small families. CDX specification brings comfort-focused appeal. Against rivals, it is a less familiar choice, worth considering for affordable space and easy driving; check condition and service history carefully.
