I'll start.
The Advanced 4WD system allows the user to select 4A (4WD Auto) and the vehicle can be driven anywhere. Highway, dirt road, snow, dry pavement... The vehicle will automatically determine when and if 4WD or 2WD is needed. Meaning when to engage the front axle.. The Advanced 4WD system...
I believe our builds are pretty similar. I'm getting green 2dr BD 2.3 Auto with Mid and 4A. I won't change my order to get it sooner. Why settle? I've had 4A in a couple vehicles and I like that it does all the thinking for me.
