I am 100% sure they are all Hasegawa, I must be mistaken on the car models. I have been looking at so many lately I am going insane. I ordered some paint from the store, when I go pick it up I will take a look again. I belive they all have engine details. there is a window on the box to show the body, maybe if I shake it gently a bit I can get a view of the parts trees.
I have found a few that are making me drool.
1. Fujimi 1/16 F40LM
2. Fujimi 1/16 288 GTO
3. Hasegawa Nissan R89C with Studio 27 metal engine details.
