Formerly having obtained License for use of Trademark and Copyrighted Designs from a Automaker, I can say if the product appears to resemble any car ever made (I know this is very open) and especially if it contains a brand name or logo... but does not contain a License Statement in the Readme or License naming the manufacturer, run away from the model and do not try to use it in a commercial venture.

For the Automaker to continue to enforce their Trademark, the License Statement must be included and normally is required to be included with any end user work, along with compensation and approval in most cases.

My experience was for a Ford Dealer Commercial and because we created a Model of the car, we had to get permission from Ford. I decided to take it a step farther, with plans on selling the model and the requirements for both me (Up front License Fees, plus a per sale fee) and the end user (authorization of release of work and per use fee) I never did sell the model.

If you want to see an example of the statements, go to any Hobby Store and read a Car Model Box... most have the License statement printed on the Box.
