The HYUNDAI SONATA (1999-01) 4DR SALOON 2.0 CDX AUTO4 is a large, four-door family saloon from Hyundai’s turn-of-the-century range. In the UK it sat as a value-focused alternative to established family cars, offering a spacious, comfortable format rather than hatchback practicality or sporty appeal. Its automatic gearbox makes everyday driving straightforward, especially in town and stop-start traffic. With room for passengers and luggage, the Sonata suits families, regular commuters and drivers wanting an easygoing used saloon. Mycarcheck.com’s sample is small: four checks covered three distinct VINs, so figures are clues, not a full picture. Those records show average mileage of 70,000 miles, about 3,000 annually, and 3.5 previous keepers. An average private-sale figure of £100 is recorded, but with so few examples it should not be treated as a reliable price. Against Ford Mondeo and Vauxhall Vectra rivals, the appeal is comfort and equipment; condition and service history matter for this Hyundai.
