Yeah, but you could go find some 1/48 trucks with interiors etc for about 3 pound each if price were your main issue, wack a machine gun and a combatant on, and you're there (Hell then the doors open too!), and you wouldnt have that issue about the bases causing troops to tower above their vehicles.
On a resin kit Im willing to overlook interior, but a plastic model really ought to have one, and it actually ends up costing Mongoose more if they have to go back and redo all their vehicles to catch up when someone else brings out an alternative.
Also these are meant to be better than 80% (Or was it 90%?) can achieve remember? Im sure most of us could black out the windows.
Still its good to have room for improvement, and the variants in colour are a good sign.
