Head gasket and evaporator leaks, which are common problems within the model you request information, are child's play compared to the nightmare and expense required to fix the 4matic system. And believe me, sooner or later, it will fail.

With the mileage on the vehicle you are interest in, I would say it will be sooner than later that the 4matic will give you trouble.

The cheapest estimate I have heard on 4matics is $4,500, some go up to $7,500 And the trick is that you cannot let the system die because the car will be dead also (unlike the evaporator, which you can just let it go and drive with the windows open in the summer).

Finally, a faulty rear self-levelling suspension will easily run you from $1,500 to $4,500 to put back in business. Again, if this system is out, your ride is basically out too. It cannot be reversed to the regular setup of the sedan and cannot be easily and cheaply fix either.

A word of advice: RUN (not walk) away from that T 4matic.
