I dont see anywhere about what ML it is?
We have 3 in the family here at the moment. A 350, 320 and a 270CDI.
Out of the surveys back in 2002 for the competition, the Merc was top for storage space. X5's have a very small boot and storage capicity.
I have the 270CDI sat in my garage here and it is slower than a wet weekend. The 320 goes nicely but seems to be having some mechanical issues at the moment including a nasty idling issue at only 115,000kms. Already had diamond tipped spark plugs replaced which cost a small fortune. The 350 is slightly more refined but as you already have a rex and a 3 door, do you need a 4x4 with all the balls?
The 55 or Brabus would be
