I think it would be a good idea to keep the salesman OUT of the picture.

Ideally, to focus on just the car while starting it up and letting it idle throughout the clip.

I would also look into potential up-sells. Maybe something like color CAR VIDEO business cards to sell each dealer for their Salesman to grab and write their name on and pass out for referrals.

That also offer some sort of a free report on the back like 'How to Buy a New or Used Car and Win!' for prospects to visit the car video site and enter their email address to receive. Which allow the dealer (or you too) to follow-up.

I really like the idea of promoting a combination of online and offline marketing to the more traditional offline dealers and merchants (see below). And have put some short videos together that didn't much time shoot or edit (especially if you go with just a slideshow). Though transferring the video can waste a lot of time if you're not careful.

Good luck,

Rod
