Your course of action depends on if your invention is a factory installed product (OEM – original equipment manufacturer) or aftermarket product. If it is OEM my guess is that EN would not be able to do much with it because EN deals with consumer products sold in retail, and probably doesn’t have established relationships in the auto industry.
If it is after market, then you have a better shot through EN. A while back, EN ran a Live Product Search for PepBoys for example.

If it is aftermarket (ie Pep Boys, Autozone, Advance Auto Parts, O’reilly’s, etc) then I would submit it to a lunch hour search and perhaps offer a suggestion ,through your submission, that EN attempt to leverage any relationships they were able to establish with Pep Boys.
I once submitted an auto industry invention to EN for the Daymond John, and Lunch Hour (twice) searches. I knew it was a long shot and it received an R4 all 3 times. EN thought it would be too expensive and too complex to develop. I’m not convinced of that, but I have tabled it as far as EN goes.
Hope this helps.
