why is the orange buick gsx so hard to find?i was able to find 5 of them,but just went back and they have a huge box of hot wheels and not one of the orange ones were in there.a orange one just sold on ebay for $17.99 and a yellow one sold for $25.00,i have a ton of yellow ones.the 87 black monte carlo ss is also hard to find,i only found one of those.
