The AUDI A6 (1997-04) 4DR SALOON 2.5 TDI SE is a large, four-door executive saloon, positioned above mainstream family cars in the UK used market. Its understated styling and roomy cabin make it a practical choice for buyers wanting premium comfort and a substantial boot, rather than a small city car or SUV. The 2.5 TDI diesel suits regular commuting, motorway journeys and family travel, with relaxed cruising and useful range often central to its appeal. Compared with similarly aged BMW 5 Series and Mercedes-Benz E-Class saloons, the A6 is known for a comfortable, refined feel and restrained design; its SE trim aims for useful equipment without sporting excess.
