I did it the same way like you. I have inherited my c64 from my brother because he lost his interest in it. I upgraded to AMIGA500(+ ?) in 1990 (?) and sold the c64. Years later I sold my AMIGA, too.
But months ago I bought two A500s and maybe I will also buy a C64 "Brotkiste" in the near future...
PS: In Germany the C64 is called "Brotkiste" = bread box
