Nice, but my children probably won't let my grandson have one because of their experience on a 2013 GLK 250 Cdi Bluetec 4 Matic. (They bought one with 40,000 miles and a RUINED DEF system). After many thousands of $$ of repairs at the dealer, they gave up and traded it in on a new Toyota Rav4. They bought theirs after seeing my 55 and how much I liked it.
