Took 3 months before installation. (I knew that from the start) I was quoted a balance of $2838.59. When i got my bill after installation, my quote was totally different, it was $3,146.70. I was charged commission twice. I already put 10% down ($246.50) now they charge commission surcharge of $554.00. A difference of $297.50 they charged me for no reason. I have called the dealer that they deal with and he said it is wrongful and he will be calling them. I have stopped the check payment! PLEASE be aware!!! We work too hard to let others scam us. It's disgraceful. User's recommendation: My receipts are beliw from orgibal quote to the day they installed. Big difference in price. BEWARE!!
