I have a nice picture of Cadillac limo from True Romance, HOWEVER it is from a deleted scene on the DVD, it wasn't in the actual cut of the film. Does it still count?

Good question. As it is on the DVD I think we could list it, by indicating that it comes from deleted scenes.
We already have similar case with a Ferrari with "2 Fast 2 Furious" if I remember well.
There is a similar case: long versions or director's cut edition. Some cars that I listed for Lethal Weapon movies may not exist in the theatrical release, as my DVDs are "Director's cut" editions, with few extra scenes. Same for the long version of Terminator 2.

Shall I go ahead and post it then?

Yes, sure
