The Mercedes-Benz GLK stands out due to its bombastic styling, eschewing the generic oblong crossover shape in favor of upright, angular bodywork. Most crossovers seem shaped by the wind. The GLK, meant to evoke the boxy G-Class S.U.V., looks as if it were left in the path of a retreating glacier. While the 2010 GLK appears blunt, its coefficient of drag is only 0.35, the same as a Porsche Cayenne and surely far better than the G-Class. Like any crossover in search of a bit of street cred, the GLK wears oversized wheels. The central control knob and seven-inch in-dash LCD screen are up-to-the-minute and quite intuitive to use. Scrolling through radio stations is particularly easy, as the display screen mimics an analog dial and the knurled control knob becomes the tuner. The interior can also be optioned up with some of the toys you'd expect on a bigger S.U.V., like dual rear-seat flat-screen TVs and a panorama glass roof that extends over the rear seats. The base rear-drive GLK is priced at $34,775. All-wheel-drive adds $2,000. It's a sign of the times when a Mercedes sport utility wagon begs to be considered from a value perspective.
