I consider the vacuum lock system to be far superior to electric locks. In almost a million miles of MB's with vacuum locks I have had two vacuum diaphragm failures that cost less than $10 each to repair and probably less than one hour labor.

The system is simple, economical, and trouble free.

To answer the question the 203 MB's have taken the step backwards to electric locks. I dread the day when I have to repair them.

Have a great day,
