I can confirm to have seen a few models that were not built by them... in fact I worked on these few models ages ago with a few friends.
For the other content I can't tell, and can't tell if they got the permissions from the original modders.
Anyway, it is not the end of the world... the models were distributed for free, and you can still find them on rfactor/gtr2/gtl forums.
As I see it, they are charging for the conversion job that takes some time to do it.
If it is legal or not, I wouldn't go down that rabbit hole... we too, about 10 - 15 years ago never get permission from Opel, VW, Ford, BMW, etc. to use their brands, blueprints and designs.
It is a hobby after all... if you wanna pay for it, do it... if not, ask around and you will get what you are asking for
It has always been some kind of grey area, and I admit my guilt for not bothering to contact the big companies to get the permissions sorted... but I never charged a penny for any of my work (hobby).
I see it as a favor to the car manufacturer... a kind of free advertisement... but of course, someone can see it from another perspective...
It is too complicated to get into such discussions... better leave it and spend some time looking around for what you need... the internet is huge and full of good people
EDIT:
No problem
@BrandonW77 ...as said, it is not a problem complying to the rules, and I didn't wanted to start a debate about that by any means.
I respect everybody's opinion and point of view... it is not an obligation to agree with them, but sharing opinions and widening our point of views can do only good to everyone of us.
So, to end this, I am asking for some indulgence if I sometimes double post... I've done it for ages, and I am used to write on the forums this way, since IRC end newsgroups times back in the '80.... quoting and answering gives me a feel of a debate, and that is not what I wan't to do... i appreciate more e free flowing conversation than a debate.
(nevertheless, I'll try to bring it down to a minimum
)
Cheers, and thanks for taking the time to answer.
