Contact local car dealers and ask them to bring their latest cars, both local and imports. The Porsche dealer , for starters?. So what if it is the Cultus et al from Suzuki?. That's what is currently available in your market for buyers. Ask the VCCCP guys to select the best of classics in Lahore for display. Same goes for the 4X4s too and modded cars. Others can display their cars in the parking area and enthusiasts can check them out there and take pics too. Just suggesting, based on what i've gathered from car shows here which are managed by events management companies and not the organizers. The organizers get the idea of a show going and that's it. For eg., the upcoming supercar show in Chennai is being put together by Parx, an events management company that organized the recently concluded Mumbai supercar show too.
