2008 Mercedes-Benz GL320 CDI compare

The cabin electronics and interface for the 2008 Mercedes-Benz GL320 CDI's infotainment system are old and have fallen far behind today's standards, but the diesel engine makes the car drive well and get incredible fuel economy for a full-size SUV.

The higher cost of diesel might make the 2012 Mercedes-Benz ML350 Bluetec's superior fuel economy a wash when compared with a gasoline version, but this truck's luxury features make it a very comfortable road tripper.

The pricey 2013 Mercedes-Benz G63 AMG is far more showpiece than practical everyday driver, but it makes quite an impression in its combination of old and new.

The 2013 Nissan Rogue SV surprises with good available safety and infotainment tech and above-average performance.

The 2013 Ford Escape Titanium is a whole new car, both inside and out, offering great tech where the rubber meets the road and unique automation technologies that make it an easy car to live with.
