Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
This is a situation where direct contact with the sales manager of a few dealerships is in order.
I run a small European car repair shop in Western NY, and have developed relationships with a few key dealerships in my area, both for service and parts reasons, and for the few new car deals that I can refer folks to
However, in your case, being a dealer yourself, this may be considered a bit of a conflict of interest to the larger new car dealers, as they are also used car dealers
But definitely some phone time, and person to person time is in order with each dealer's sales manager, and/or general manager
