In My Life,
Yes, there are reenactors for several different wars, some definitely not as popular as others. I believe Civil and WWII are the most popular. Anyways, here's how he became interested: him and his younger brother were always into army things, but not yet particularly WWII. One day they somehow met a guy who was a WWII reenactor and collector and who also served overseas in Iraq. He turned them on to WWII specifically. My boyfriend was about 12 at the time. Now he's almost 26 and still as dedicated as ever! And still is friends with the guy who got him interested.
My boyfriend got the jeep when he was 15 years old. An older guy who is the leader of their WWII troop found it in an abandoned airport! And gave it to him. Over the years, they all have acquired vehicles and spend a lot of time working on them. Here is a picture of the jeep when it was found. Nowadays, much of the parts on it are not original, but extremely true to the style!
