I have been using the car care club for about 2 years and I am very happy with it. It works best on your top customers it really brings the average Invoice up.Bottom feeders just use all the free stuff.Now I only offer to it to my better customers,it also keeps them from going any where else. When you sign up Ron has a sales letter for you to send out to your customers.after seeing my results I would recommend you just send out to your top 20% to begin with.I sold 100 in the first 2 months.The way I keep track of it,when I sell one it goes under labor with no one attached to it.then when they use it I give the discount under labor. when I looked at the difference in labor profit its about 1% lower with car care club this year,but my gross profit parts and labor is up $3000 per month this year.You can also just raise your labor rate to off set it.
