 We drove 2 glks for a total of 7 years. The glc was a bad mistake.  The lever to lower the front of driver seat is non functional. The car throws you around when going around curves on the interstate going 70. The car practically throws you out when going over a speed bump. Had a flat tire and had to wait a week for a replacement. Bluetooth won't stay connected. Garmin is worse than having no navigation.  I could go on and on.  Don't do it!
