Pros
Organization and structure: if you like systems, reports, word tracks and a general "one size fits all" approach to running a business from Florida to Washington, you might enjoy it. They can take someone with no experience in the automotive industry and train them to be functional in nearly any position.
Cons
Typical modern corporate problems of accountants and MBAs running a business. The primary goal is to maximize shareholder revenue and push as much money as possible to the very top of the food chain. They excel at that. Comp reduction is a constant focus, and they are very creative at it. New pay plans often come out several times a year, always with a cut somewhere. Systems, policies and procedures have changed many times over the years, constantly trying to re-invent the wheel in an industry that is largely figured out. Store level managers have very little authority. When they purchase successful stores they often ruin them by cutting and cutting and cutting until the people there that knew how to run everything in an excellent way leave. Then they resurrect it to a level of homogenized mediocrity and applaud themselves at how they "fixed a broken store". Very sad to see, like watching a group of haughty inexperienced children trying to accomplish a goal.
