Increasing Service Traffic

We have 14 Dealerships. We are conducting a meeting with all of our Managers. I am looking for companies that would like to present their ideas to our Managers on the subject of increasing service traffic.
I am looking for something unique and different. We already do the solid basic standard activities ie: Direct mail service follow up realizing return rates of 28% to 54% - Calling all customers within 72 hours of their service visit from our Corporate Call Center - We do additional direct mail pieces with various offers and discounts.
Are dealerships are located from California to West Virginia.
Please e-mail me if you think you have something that can make a difference (jastarkey@martingp.com)
Thanks
