The average private-sale value is £2,800, with 166,000 miles recorded and 10,000 miles driven annually. An average 5.6 previous keepers makes condition and service history especially important: these are well-used cars, so check each car’s background carefully in person before you buy.

S line trim brings a sportier look and feel, helping it stand out from comfort-focused rivals in its class. Look closely at upkeep and running costs; this is an appealing saloon, not a low-mileage bargain.
