Yesterday we got the car, the cocoa brown GLA 250 4MATIC, premium, multimedia, 19" wheels, blind assist, etc. It is, indeed, a very nice and entertaining machine. The first bit of observation. Due to the delivery delay, we got for week a loaner GLA 250 ( credit to the MB good service style). The loaner GLA was basic 2015, fw only. I was surprised to find out that the first drive of our 2016 4MATIC appeared to be noticeably different, including the feel of the road and stop and go dynamic. Apparently, the default driving mode appeared to be no longer Eco, but Comfort, a kind of intermediate state between Eco and Sport. I found the Comfort mode being more responsive and interesting. The softer feel of the road is a bit harder to explain. The loaner GLA wheels were 18", supposingly providing softer ride than our new GLA 19" wheels. Could that be the 4MATIC effect? Anyhow, the big driving will start soon. I am looking to sharing the impressions.
