Cars are our passion, and we will do everything in our power to make sure you come into the shop and leave happy.

I had intended to send you an email as soon as I caught up with everything from being out on Friday. Based on your level of customer service I am not shocked to hear from you first. 

I do not think I could physically be any happier with the car. The improvement in drivability is beyond words. Everything from sitting there idling to mashing the go pedal, feels totally improved. Is it weird to feel that it finally drives like it was supposed to?

It was a real pleasure to do business with you guys. I have never felt so welcome and appreciated. It was awesome how you took your time and explained what was going on. I felt involved throughout the entire process. 

It is definitely a drive to get there from Cary however, it is a drive I will make over and over again with a huge smile on my face. 

A very big "Thank You" to both you and Nick!!!"
