Hi,
I am seriously looking at buying a M class as I need 7 seats.
I have heard that the build quality is not very good. I have about 15k to spend which seems to be the W or X reg bracket.

1. Pls can some one advise what is the best engine?
2. What are the main problems or weak points?
3. Are there any good websites on the M class?
4. When did the facelift occur after the initial version in 98.

Pls help
