MERCEDES-BENZ S CLASS (1999-06) S320 4DR LIMOUSINE 3.2 AUTO LWB
Buyer's Guide & Data from our Checks
The MERCEDES-BENZ S CLASS (1999-06) S320 4DR LIMOUSINE 3.2 AUTO LWB is a luxury saloon with an extended wheelbase giving rear passengers extra room. In Britain it sits among executive flagships, offering a spacious, formal alternative to the BMW 7 Series and Jaguar XJ, rather than an everyday family hatchback.
It suits buyers seeking comfort on long journeys, chauffeur-style use or relaxed daily travel, especially those prioritising rear-seat space and a smooth automatic drive over low running costs. Mycarcheck data records 110 checks across 50 distinct VINs, with an average recorded mileage of 120,000 miles and annual mileage of 4,000.
The average private-sale estimate is £1,400, while records show about six previous keepers, making a history check worthwhile. The S320 is known for quiet comfort and prestige; as an older luxury car, condition and upkeep matter, so check service records carefully before buying and budget for potentially higher ownership costs.
Considering an S-Class S320? Outstanding finance, write-offs, hidden damage, mileage discrepancies or theft could turn a luxury buy into a costly mistake. Enter the reg now and check before you commit.
