Mercedes M-class?
 

Hi,
I would like some advise. I currently own a 1998 S280, but due to a large family I need more seats. I am considering buying a M Class (with family pack), but have heard that they are not well made, especially the earlier ones (1998-2000).
Can some one please give me advise on these vehicles, as I dont know much about them.
Also which is the best model?. I will not be taking it off road.

Many thanks
Amolak
