Traded in our BMW X3. Overall, the GLK is a better SUV. It holds more cargo, has good power and never feels heavy. The biggest problem to report has to do with electronic problems- from the power seats to the rear latch to the A/C controls which shorted out. Already needed additional oil and the system check light alerted us of engine/EC problems. Build quality is low to average. The COMAND info system is good but not great:the knob is placed in a very odd position behind shifter. Why? The brakes are soft and fade from highway speeds. It needs premium gas and at 14.1 MPG average, it needs plenty of gas. There is no place for cell phones- only in small cup holders. Little back seat room.
Quick, nimble and smaller than ML. Decent cargo area compared to BMW X3. Nice exterior design. Good side profile and proportions. COMAND is better an iDrive by a mile. Sat radio is easy to use. Bluetooth and iPod controls are easy to install.
Quality is disappointing for a $48,300 SUV. Although our BMW was not the most reliable either, it did feel well built. Reliability has so far been poor.Time will tell. Many people complain about Mercedes' reliability record so this may be the price to pay for 3 pointed star. MPG at 14 is absurd.
