Looking for a premium crossover but don’t want to helm the USS Navigator? Mercedes-Benz stuffs the small second generation GLA 250 with lots of luxury and tons of tech… if you option it properly. This is a serious competitor to Audi Q3, BMW X1 and X2, Cadillac XT4 and Lexus UX. Tom Voelk takes a look a a well equipped 4MATIC model, that carves a corner better than you might think.
