We use this report to see which ZIP codes and cities generate the most customers and highest profits for your dealership. For accurate results, we capture each customer's address at the time they purchased, leased, or serviced their vehicle - using their current address wouldn't give us the right picture. We then calculate the market penetration for each ZIP code by comparing the population against the number of transactions from that area. We don't advertise to low-performing ZIP codes, even if they're closer to you than areas that have historically performed much better.
