hobbydb.com is an online database for just about anything collectible. They are building a giant database of every one ever made...and you can add to it, too. Models and toys can be found by brand, scale, color, production years and many other factors. Plus, there are real vehicles and anything that relates to them such as manuals, brochures and ads. All those things are interrelated so you can search for exactly what you want. As an example, click on the link to see Ford Mustang Muscle Machines (includes Muscle Machines from the previous manufacturer, too).
In addition to the many collectors who independently posted Maisto die-casts, I've been filling in many of the missing ones. Despite our best efforts some styles and colors still need to be included. To make it complete we need you to check your collection and upload photos and information if it is not in the database. It's free and you'll be helping make this a great site to see everything that has been produced.
Maybe you'll find that something that you collect was made but you didn't know about it until you saw it on hobbydb.com. Find out more here: http://info.hobbydb.com/the-hobbydb-manifesto/
