Contact local car dealerships and see if they are willing to bring a few luxury cars down for a test drive course. Set up cones in a parking lot. Charge people to take a test drive around the lot to see what it is like to drive that ultra luxury vehicle You can encourage dealership participation by making sure they know they can bring a sales person to give people the sales pitch.. Get niche vehicles to add a different spin. Bring in a limousine, or an electric car. Look for vehicles that the average driver doesn’t have an opportunity to drive. See about having a dealership bring in a rugged or off-road type vehicle. This is especially good if you can set up, or have access to an off-road style obstacle course. Find out if there is a local military base or VFW hall that can bring in some military equipment. Who wouldn’t want to pay for a ride a historic tank?
