I didn't suggested it, because i'm lazy to search for info or something like that. Also it is not something i demand, but something that came up to my mind once i was looking through pages, and thought it might be a good idea. If you don't have time for that, someone else might be interested in writing it.
Stats associated with vehicles are speed and armament only. I thought of something like armour values, theatres on which was vehicle used, strong and weak attributes, and maybe something like explaining difference between similar vehicles like Panther ausf. A/D, or difference between M4A1, M4A3 and Jumbo.
If you think it is completely pointless, well...it's just a suggestion.
