I brought my 2013 CTS-V to Cordes for Stage 1 mods. I had been out of "the game" for 3 years and all the faces had changed. It's a strange feeling handing the keys to a $70k car to a complete stranger who's going to modify it.....there are no guarantees there has to be confidence and trust. Guys I knew recommended Cordes and I am totally satisfied. Good communication, good price, quality work and of course......results. Thanks Joe
