I don't want to crap in anyones bucket either, but the truth is that you just can't get them all.

15 - 20 years ago, maybe.....

Just collect what you want and enjoy. If you can afford the others or can't find them, go for it.

I still try to pick up ANY Oldsmobiles that I don't have. Pick a niche that interests you.

After a few years, you won't be able to enjoy them in a box stored away somewhere anyway.
