They have an amazing collection of vehicles and many of them could have driven right out of the game. I couldn't believe how many they had which I was familiar with from COH units and how good a condition they are in.
Just as an example they have an IS-2, T34/76 and 85, various Sherman variants, an M18, a Comet, a Crocodile, a Churchill, a 222 AC, Panther, StuG III with armor skirts, a ketten, a Nebel and much more.
They're also running a contest right now where you can win a 2 day experience that includes driving actual M24 Chaffee, M4A3 Sherman and an M26 Pershing!
Disclaimer: I have no affiliation with this organization. I was just very impressed with the collection and how it brought so many of the CoH units to life for me. And I think the tank driving experience is very cool.
