I just found this site for model z cars:

http://www.ne.jp/asahi/z32/na/

Use the menu on the left, and the next button to get the next menu of models (there's 3 of them).

This is the most complete list of model z cars by manufacturer i've seen, and they are with photos.

Those tomica cars can get really expensive. I have about ten with boxes and I paid way to much for a few of them. They are quite cute though.

If you guys are interesting in plastic model kits, I found this place to be excellent. http://www.hlj.com/ They send the kits to you and don't let the "out of stock" worry you. I have purchased a dozen kits from them (everything you see "rare, rare, rare" on eBay) at quite reasonable prices including postage from Japan. Although I had to wait for a while on some kits, I eventually got everything I ordered. The kits are all first rate.

What is the detail like on the Dyosho Z432-R? I have the Fujimi 432-R kit, and everything has lots of detail except the interior. I would like to get one of the Dyosho ones as well.
