Bob K, I can not comment about the things you are learning from ATI however coming from the perspective of someone who has taken control of their automotive management and shop owner education into their own hands as well as the help of a consultation company coach I would like to pose to you the question of really looking at the factors as to why you are feeling the negative effects of Down business. If you are up one month and down the other you have to look into your marketing efforts both new customer and CRM. when speaking about profitability with higher ARO and a deceased car count well that is a natural occurrence. You have a finite amount of labor hours to sell so by nature if you are selling more hours per car you will have to have a decrease in car count since those sold hours are concentrated on a smaller number of cars opposed to being spread out. Also losing customers due to a price increase, that's a tricky one. In my experience I have increased prices dramatically and not felt any detrimental effects. You have #1 match the value to your price. You have to make it worth it for your customers to be paying a higher price. Also the ones you lose due to price increases may no longer fit in your mould as an ideal customer any longer. Price and money are a matter of perception. The great majority if your clientele have money to spend. I often say this to my own staff, you can spend $5 and feel like you got ripped off or spend $5000 and feel great like you got your money's worth. It all comes down to a matter of perception. The ultimate goal is to make your customers perceive that they are getting tremendous value from their purchase/investment with you. That is the golden answer.
