Any modern tank would be nice.
Modern: Merkava IV, Russian T-90,
Italian Ariete MBT, AMX-30, Leclerc Mk 2, M60A3. Any of these would be nice
Really great tanks and totally unique would be any of the following, it would also be a nice addition showing the beginning of tank design and are well known enough to generate interest. A plus is that nobody else has done them, even the put together kits are hard to come by, of course that could be an argument against it also, but from a collectors point of view I don't believe so.
Unique: World War I tanks: British Mark V
Renault FT-17
German A7V
