As the title says, what makes you happy?
I love getting new diecast. Yes, I collect little toy cars. I started out collecting Hot Wheels, Matchbox and Majorette when I was still a little kid. Since then, I've gotten into the more detailed brands such as M2, Johnny Lightning and Auto World. I still collect Hot Wheels, but as I get older, I've started to really appreciate the real cars that the toys are based on. As part of my birthday, I went to one of my favorite museums, and while I bought Hot Wheels, I also purchased several more high-quality pieces. I know this seems odd, but it's just who I am. Real cars also make me happy, and if there's a diecast version of one out there, you can bet I'll find it.
