I don't think the extra two years of time make it any less impratical than it was in Ghostbusters 2.
Maybe, but let's be honest, the thing looks a lot less top heavy with half of that crap removed from it. The car's a lot more streamlined again and looks more professional in my mind. It still has the emergency lights on it, but doesn't look like a mobile disco.
It's updated, but still retains it's recognisable profile.
