...I hoped it might be to announce a buy back of the GLK like my neighbour got from VW
Buy back? Not sure that it will come. They reassured me (directly from MB of Canada) that they meet and exceed gov regulations for diesel. Up to now, as much as I understand, no country have done a legal pursuit against them. What do believe on your side?
Personally, I am very satisfied of my GLK 250. On highways it can go down as low as 5.6L/100 km. This is very good for the weight with the 4Matic!
