Wah you guys are really desperate to get the models lar. Going to the extend of paying extra when you know its not worth that much, whoa, really enthusiastic.
Anyway, I just wanna tell you all to be patient. I was in a similar situation early this year looking for Kimi's MP4-20. Went to all possible places that could possibly stock these diecast models in their inventory, each time going home disappointed. I really wanted to get one because I thought these things were limited edition sutff. After a month searching, I thought wah game over lar.
Some time later, when the Sepang F1 craze was over, I went back to a shop in BTS, where I previously saw Fisi's R25, Ruben's F2005. And hey, guess what? Schumi's F2005 was there, Kimi's MP4-20 was there. Even Fernando's R25 was there. All the hard-to-find stuff were there!
So what I'm trying to say is, these stuff are hot now, coz they're just released recently. Demand is really high as expected. When the demand starts to fade, there'll be plenty of stock. Besides, only those major supermarkets were carrying them now. Toy shops will have them in their inventory later anyway.
Btw, you can try call Malaysia's Mattel distributor if you wanna know the availability of the diecasts. At least thats what I did last time. Good luck ppl

I'm gonna take my time searching
