I have a heavy gauge die-cast metal with plastic parts yellow volkswagen - 1:24 with doors openable and free wheeling that I picked up ~ 25++ years ago - still boxed - the company name is not on the box -just a logo with the letter S it's item number is SS7707W and it was made in china "with permission of volkswagon ag"

I don't really collect die-cast - I am going to post this on price check - but wanted to get a feel for how collectible these are - ??
