About the author

32 years inside
the industry.
Now on your side.

I started at General Motors in 1992. Spent a decade running service operations at Jiffy Lube. Learned the parts business from the inside at AutoZone. Then became VP of Operations at Firestone Complete Auto Care.

I've sat in dealer training sessions. I know their scripts. I've reviewed F&I pricing structures. I know what margin looks like on every add-on they sell. Now I'm giving you all of it.
