Just had my 2006 M3 done. I couldn't ask for a better job. I chose 35%...not too dark and not too light. \r
Comparison: When looking through my other car's tint not done at Best Image, my rear view images were blurry. With the brand Best Image used on my car (I believe 3M), the viewing is clear and crisp. I am sure it's also due to their craftsmanship.\r
I've learned that they have commercial accounts other than private parties. That should tell you something about confidence in their work and being able to maintain working relationships. I will be one of those repeat customers and refer them work.\r
Thanks Best Image!
