Which used Mercedes V-Class estate should I buy?
Standard equipment on entry-level SE examples is actually very good, including front and rear parking sensors, a rear-view camera, heated leather front seats, cruise control and sat-nav. Sport is a little better, providing full LED headlights, headlight washers and upgraded Nappa leather upholstery. AMG Line is more of a styling package, because it adds bigger (19in) alloy wheels, sporty exterior trinkets and carbonfibre-look interior trim pieces.
On the whole, a Sport model is the best choice, because it gets you lots of kit without being more expensive than an SE on the used market.
