Yes the early releases of Minichamps may be a bit toyish but their newer release such as the Centurion and T-72 are really great looking.
Minichamps - Mike's Diecast Tanks and Armour
Scroll down to near bottom to take a look at Minichamps Centurion and T-72.
The site post quite a large picture of them. Simply beautiful. So I say Minichamps is improving themselves.
I decided to post some pics myself from the site
British Centurion
East Germany T-72
Note that both tanks have black tracks instead of the usual silver.
Plus each of the wheels rotate, the threads are metal just like the real ones and the suspensions work. It is really a tank. LOL
