Hi, hisstoryman.

I do have a partial list that I can email to you if you wish. 

Its a set of cached pages containing around 120 of the items you are concerned about, including images for quick identification. You can mail me at- lemon6seven@gmail.com.

I'm pretty late at reading this, but most of dalmatiner's posted car models can be found at DMI.  Free, but almost all of them are no commercial use, unless you want to go to the paid models, which some will even furnish in the format of your choice, when asked.  I haven't done that, but I also don't do commercial renders. 

Do you mean http://www.dmi-3d.net?

Yes.  From his first postings, I saw the models he put up identical to those on DMI.  As I downloaded them from dmi already, not hard to tell.  Not hard to put into poser props either, just rescale, probably have to mess with the textures, adding a few motions isn't hard either if the mesh is made so you can.  Not for commercial use, but I don't do commercial anyhow, no biggie to me.  Dalmatiner's scaling was also pretty bad.

Dalmatiner is back now in 2015, and posting on Renderosity's Freestuff pages under the name 101Doberman. Because of his history, I am wary of downloading any of his newly shared items.

I occasionally download models from Sketchup and convert them to .obj format for my own amusement - attempt to fix them up in Carrara - but it doesn't often work well because Sketchup uses n-gons, while Poser and DS Studio can't deal with any polygons with more than four sides. 

Not sure why anyone would go to the trouble.

FWIW 101Doberman's profile at Renderosity has no Freestuff or Marketplace items as of this post.
