I just checked, and I havn't got anything off him, but I'm pretty sure he had some cars I was going to get at 1 time, as it sounds really familliar...
theres so many diffrent things that makes 1 hotwheels worth more than the other.. I really don't buy them for the value myself, I buy what I like and, never open them so I know they will retain value, but I could have a real gem hanging right next to 1 that is worthless.. I do know that wheel diffrences, chassis/ base diffrences and color will all effect the value along side the stripe diffrences... The basic base is a Malaysia base, but there are also bases from Thailand which are found on the higher end or specialty cars, like the since 68 cars or classics series.. there may be other bases but I'm not aware of them.. all mine are from Malaysia or Thailand.. with the exception of the original '68 Redline I have which is USA.. I have an unopened '86 edition of the Old # 5 and altho it's a heavier car with a painted and not chrome/ aluminum color base, it is a Malaysia base, and the stamp on the car is 1980, so Malaysia goes back to at least 1980
