I've had mine for 5 years, yes well aware of the wave. So if you didn't know, the history behind that is after is the jeep was a vehicle of choice in most major wars and most of the army guys back home either drove the local base ones so they used to give the waive at each other knowing they where most likely military brothers driving them.... now it seems to be the new mid life crisis vehicle... I think that's worth a wave...Is the Sahara your first Jeep?
You know you have to do the "Jeep Wave" right?
At my dealership it's part of the get-to-know-your-vehicle tour ... LOL
