“The crew is nothing short of spectacular. This was the best experience that I had with a mechanic yet. They took great care of my car, but also care for me as a person. While my vehicle was being repaired, they helped with car rental rates and ensure I could drive my son around when he got sick. Thank you Guarantee! You guys are the best!!”-- Marcia R.
