Originally according to the portraits that came out for 2009 models in matchbox website, the new truck wheels (used in 2008 Garbage truck) were supposed to be fitted for Unimog, Ladder truck as well as the '97 Defender. All would've looked fantastic with those new wheels, but then, they eventually used back the old wheels for some reason that David did mention in mcch website long back.
Now I wonder if the City Bus and Cement Mixer in yellow planned for this year would also use back the old wheels instead. They would look great with those new truck wheels as pictured in matchbox website. But is it going to happen???
