I guess the locking logics have been changed several times in last decade.
When we test-drove ML in 97 it had automatic locks.
Our delivered year later didn't.
My 99 E-classe locks the doors automatically with the ignition on, while 97 E doesn't.
I know newer models can be programmed one way, or the other, but we might be stuck with what we have on older ones.
