Collecting off and on over there years and the main frustration is a tracking system. I can’t believe by now no one has come out with a good database program for keeping a good inventory of what you have. My last Hot Wheels fever was in 2012 and I have the Excel database I created from data dumps of the www.southtexasdiecast.com/hwguide.html#castinglist site. The other option is dumping the cells from hotwheels.wikia.com/wiki/Category:Hot_Wheels_by_Year .
I saw a post that spoke an APP but it was for Apple only and I have Droid. Mattel came out with software for the 30th birthday that sold with a drag bus but they never updated the software and since its Windows 9x it won’t even install on Windows 10.
I keep buying duplicates because I not always 100% sure of what I have. I have been taking pictures of my recent buys laid out on tables to zoom in and check.
Now the hotwheelscollectors.mattel.com has options to build a list but I’m sorry this is pretty bad. It’s too buggy and slow. I can never seem to edit the list. Now if you look on the back of a HW care they give you a code like KN21G to build a collection on the HW site but they don’t make that easy to find. You can sit at you PC for an hour trying to find it. When the real site for this is play.hotwheels.com/en-us/index.html Once you try this out you realize this isn’t going to work for you. Try using it on your phone and you will just give up with the slowness of this system.
So what are you guys doing?
