"I’m not sure whether this review is technically for the shop that completed my installation or for Smart Start, but I feel both deserve recognition. Everyone I dealt with was incredibly professional, helpful, knowledgeable, and genuinely committed to making the entire experience as smooth as possible.
A HUGE thank you to American Motor Auto Storage for the outstanding work they did on my brand-new BMW. Wade was absolutely phenomenal! He knows exactly what he’s doing, takes pride in his work, and went above and beyond!
After having such a frustrating and horrible experience with Intoxalock, I was honestly dreading having to go through this process again. Wade completely changed that experience for me. His professionalism, expertise, patience, and attention to detail made all the difference.
The price was a little higher than I initially expected, but honestly, I didn’t mind paying a bit more for this level of professionalism and quality workmanship. It was worth every single penny.
I truly cannot thank Wade at American Motor Auto Storage and Smart start enough for taking such great care of my BMW and making this process such a positive experience.
Thank you from the bottom of my heart! I’m truly grateful and will absolutely recommend you to anyone looking for someone they can trust with their investment (car). 🙏🏼❤️"
