I was very surprised to discover the extent of the damage done to my car after having a simple 75 dollar install done......I'm now looking at 7500 dollars to repair the damage to my car. Thanks to their utter and inexcusable incompetence, virtually all the electronic safety features on my car have been rendered inoperable. I'm hoping they plan to pay any medical bills incurred should some occupant get injured should there ever be an accident. Modern cars have very complex electrical systems...especially luxury brands like mine. If you drive a Mercedes, Beamer, or Lexus, do not let them near your car or you will be very sorry. And if they have already damaged your car, you are welcome to contact me to participate in the legal actions I will take.
