The 1998 ML320 was a ground-breaking vehicle when it was first introduced and I had to have one. The early production models did have a few minor annoyances(transfer case, various squeeks and rattles) but reliability was never a concern. Overall this is one of the best vehicles I have ever owned. I highly recommend it to anyone in the market for a rugged yet elegant SUV.
My overall favorite feature is the 4ETS traction control system. It will take power from the wheels that are slipping and send extra power to the wheels with traction.
