When you write an email, you know how you can "add vehicle" and it generates a little brochure under your message? Ok, there should be a feature that allows you to have that automatically done within a template. So that your message + the brochure is automatically included for the stock number listed in the profile.
Saves you a lot of time when combing through hundreds of leads and emailing. The benefit is pretty clear: Instant brochure added and time saver and more creative emails. Cons: I can't think of any reason why it would be a detriment.
