Geoffrey Thomas
2007 Audi RS4

Aaron Marshall is a “Jedi” when it comes to Audi tuning (or any tuning I’m sure, I only have experience with my Audi). He is the only one I trust to work on my RS4. I feel confident taking my car to High Plains Raceway and pushing the limits of performance knowing Aaron has checked every detail of my car before giving it back to me.
