Car show proposal

Start one. Get your car friends together and make it happen.
That's always a good option and plan. Especially if you can get a local business interested. Like a pizzeria. Bar/pub. Or any that has some space. Advertise at that business, as well as, car sites and Facebook. The first year will be small. But you would be surprised how big it grow. Even to the point of needing a bigger event area.
