TRU had a special on today - buy five regular HWs for 10 bucks and get one model worth five bucks for free. They even had new stock, but due to work commitments, I couldn't get there until late in the afternoon. All the best stuff was of course gone - but I managed to find some cars I was missing - the picture pretty much explains it, most of it has been shown here before I think:
The special model turned out to be a "Carbonated" special release to celebrate Chinese New Year - 2015 being the Year of the Goat. I might leave this one in the blister - the car itself is pretty unremarkable.
