I wave at pretty much everybody... regardless of what Jeep they drive. I have owned a variety of Jeeps over the years. Mostly stock but all wheeled. From a old lifted CJ5 with no carpet, doors, or top to a stock grand wagoneer, a Jeepster, a ZJ, and others. I never know where someone is in live. Some ride stock because they don't have the money to pay someone to mod it, don't have the skills/tools/place to mod it themselves. Some mod them and never take them on the trails (they even sell stickers that look like mud for that "fresh off the trail" look).
Last night, I bought another Jeep... a used Liberty which will hold the 3 carseats. My budget doesn't allow for a 4-door wrangler nor do I have the tools to keep an older wagoneer up and running as dd and out on the trails. I doubt I will mod it much but will wheel it as much as possible.
I wave at pretty much everyone... 'cause I have been in both driver's seats of the Jeep wave.
