Enlarge (credit: Marlowe Bangeman) The Q5 has long been one of Audi’s best-selling models in the US. And what’s not to like? It’s a respectable-looking and functional mid-size crossover, slotting in between the bite-size Q3 and the three-row Audi Q7. With a base MSRP of $42,475, the Q5 competes with stalwarts like the BMW X3, Lexus RX450, and Acura RDX, as well as upstarts like the Alfa Romeo Stelvio (look for our review soon).
