I going to get my car(A4) and my girlz car (accord) tinted at this place between laurel and columbia. $160 for each car. Now thats a deal.
they do good job. My friend had his car done there last year.

My friend got a black tint with a semi metalic shine. Think called titanium tint. not that mirror crap

or a reputable business. I am thinking about tint for my audi allroad, but I am picky and insist on quality work.
