It's okay to show the model, just not the brand. If you are using a lot of the same car, you can do what I did. I took the original grill off my GMC Yukon and replaced it with an after-market grill with no GMC on it. Cost me $50 from Ebay and $40 for my mechanic to put it on. You will see on many TV shows, the crew just tape over the brand.
