Feeling Young Again Collecting Diecast Tomica

Just making a fun run when I finally getting my first two collection of this Random Diecast, Matchbox Hot wheels or Tomica and others But what makes my taste is what I will only buy. So you know when my first pick is Tomica it really means I am into serious Details. Smaller diecast is easier to find and to Place in a small area and plus it makes it look professional. I don't know about that, but that is how I felt it when I do.

What is your favorite collection? Do you also have some collectible toys you enjoy as a hobby? For me, I am just starting here and maybe you can also advice me about what else to keep in mind when in terms of collecting such toy cars.
