Whether it will build traffic fast I can't say but I like to run an oil change with a free tire rotation offer. Not too cheap but cheap enough to be considered a bargain. I think this kind of ad accomplishes two things. First it gives me a chance to get the wheels off the car where I can find brakes, suspension, or tire related problems. We can then tell the customer we NOTICED these in the course of the tire rotation. If I don't get the sale right then I haved planted seeds for future sales and some of this I get back in the weeks and months that follow. Secondly, the person who is interested in a tire rotation and not just a cheap oil change is someone who is interested in taking care of their vehicle. They have the potential to be a good customer. The problem with so many cheap oil change coupon customers is they don't want ANYTHING but a cheap oil change. I have even had customers tell me to not look at anything else. I don't want these people as my customers.
