Looking for some tips on upselling in the service lane. Im currently SA for the Lube Tech line so I get a lot of "coupon customers" and people who want to be in and out real fast. I always review their history before they get there so I can be prepared when the walk in to make recommendations. When trying to explain flushes one method I use to explain say an "engine flush" is that its much like the human body, after many years "plaque" builds up and needs to be removed by flushing. The longer they wait to do it the more buildup there is and more restricted the flow of oil becomes. Many seem to respond well to this. I do find that most of my customers are already shaking their heads "no" before I even get the pitch out. Much of this may have to do with it being the fact that they are in for an "express" lube and want to get out of there, my being a new face(trust), or just the current economic situation. Any tips would be much appreciated.
