MediaTrac today announced the results of a new comprehensive study of 72 automotive dealerships and over 6 million repair order transactions from December 1, 2010 through February 29, 2012, which proves that customers choose to stay longer, spend more and repurchase more often at dealerships that reward their patronage. The results are covered in a new eBook: "The Hard Facts & Financial Impact Report - Auto Dealership Loyalty Programs & the Effects They Have on Profitability."
