Your calculations are off by some margin. Assuming 312kg per car, it would take 3962 minis to transport it all, somewhat more than the 4 you accounted for. Of course you could do this with 4 cars over a thousand round trips - I'm not sure which option is most likely to lead to success, I suspect both might arouse suspicion.

D'oh! I just realized my mistake. For some reason I equated metric ton with kilogram in my math.
