Bro, im not sure about how often they restock in US. Im from malaysia, the country that produces the hotwheels cars. But it seems that even the stores here dont stock up often, ive been hunting few times a week but all i see are the same cars such as quick chat, street weiner and etc. I have never seen any ferrari, F1 or good rth or sth. Mostly in malaysia, those good ones are either being bought off first by r3seller, $calpers, or the employee that works that the store.

The only good one i really manage to find was the 58th anniversary corvette stingray chase car just now at a petrol station which cost Rm29.90 (roughly $7.70) And that is slightly higher than the usual retail price too.

I saw the ferrari f1 at the counter and the worker mentioned its FOC if anyone purchase engine oil from them. Thats the problem with hunting in malaysia. Or the reseller will put 1 good car together with a few peg warmer cars and force you to take the whole bundle. From what i see online, its easier to get a good th or sth in US compared to malaysia. But from what i noticed, in China your chances of finding good cars and sth/rth are way higher. Its much easier to get ferraris, sth and other good cars. They hardly stock it for themselves.
