Sounds weird, but do a little searching in the McDonalds catalogs etc. Match Box made numerous Hot Wheels for them over the years. I had a friend who managed a mickey Ds that brought me home lots of the toys. I've got 2 or 2 1/2 boxes in the garage and there are a few like bat mobile that I wasn't able to find on the collector sites. So give that a looksee. You might look at the non red lines too. A buddy told me he used to take redline wheels and some SS wire from he hobby shop and change the wheels to make them appear rare. Hope that gives you a few ideas! That's all the help I can give you!
