I still think it is all about getting people on the phone. When it comes to email, the national email open rate is somewhere about 11%, which means that people ignore about 89% of their emails. Can you blame them? All of the useless spam and junk that hits our email everyday can get very annoying. Email is good to try to get a customer engaged and if used properly it will help get the customer on the phone.
When it comes to pricing we need to remember that only about 20-25% of customers are solely motivated on price. However, people still use price as a barrier. This scares off a lot of untrained or improperly trained people in the business which leads them to give away gross. The important thing to do is to look at the big picture and find out what is really the reason why they want to buy a vehicle. Also, don't forget to sell them on a value package proposition. If you build value, reasonable consumer will ultimatley buy from you.
The bottom line is that you need to separate yourself from the competition. If five dealers in one area are doing the same thing, do something different to peak the customer's curiousity. At that point, you will succeed.
