Oh man... I've got a lot of em. I recently switched rooms at the house though and out almost all of em in storage.
I never look for certain series or types or whatever they are called.
Just a life long car guy so if I see one's of particular cars I like I tend to get those.
I'm always on the lookout for ae86 corollas, 240sx's, mr2's, and civic hatchback.
Matchbox is the only one thats making aw11's that I can find. I've got a ton of them. Aw11 is the 85-89 Toyota mr2. Thats what I've got, an 86 Toyota mr2 (real car). Matchbox also sells the lotus europa which is what my father has. His is a 71. Thats the only 2 Matchbox cars I buy and its just because we own the real deals.
I recently got into modding the darn things. I got a silver aw11 (mr2) and bought a better model of a civic to rob the "jdm" 4 spoke black wheels off of. I've drilled amd tapped the mr2 and swapped the black wheels to the mr2 and lowered it.
