I'm sorta new to the whole die-cast collecting thing, and I just had a couple of MM questions.
What kind of MM are rare and "valueble"?
I have a few '69 Boss 302's. Are any of these worth anything?
I know there used to be some kits that you could buy for them that had different wheels and exhaust pipes, but I couldn't get some of them to work. Especially the exhaust pipes, it felt like I was ripping the chassis apart when I tried to remove them. Any advice?

The MM thread on Chase cars probably answers the "rare" question.

I haven't tried any of the MM kits, nor tried to disassemble. There have been some threads in the past on how to disassemble a MM. You may want to search through the old MM threads.

the early unpainted or raw ones,then what the white tire grocery getters?:confused:
