The Aeon department store in the mall near my house had a buy 3 get 1 free + 10% discount on all cars deal, so I figured why not.
Didn't expect to get the '15 Mustang though. How the deal works is that you pay for the 3 cars and go to the toy testing counter to redeem the free car. I was rather surprised to see that the handful of free cars left were some orange 934 RSRs, red 993 GT2s, yellow F12s, a silver SN95 Mustang and the '15 Mustang I chose. So that was why they kept them hidden... scalpers here love those. Except for the SN95.
