Rover Classic Saab Classic VSB Enterprises Changed terms of the deal and kept my deposit after we agreed on price Staten Island New York

Just wanted to let everyone know about my experiences with Rover Classics in Staten Island, NY. I was looking to purchase a 1989 Range Rover County with them that I saw on ebay. After inquiring on the vehicle and speaking with Mike I agreed to purchase the vehicle for a total out the door price of $12,700. This included shipping to Texas. 

I then asked him to send me an invoice and he replied, very rudely, saying he won't send an invoice unless I send him a $500 deposit. I was surprised at his response and felt he was being rude but at that time nothing more. So, I spoke with him just to confirm the condition of the vehicle and the price and afterwards I sent him the deposit. 

After sending him the deposit he sends me an invoice for a HIGHER amount. I said this is different than the amount we agreed on - he suggested that these are all dealer fees that are listed on his website. I told him we had agreed upon an out the door price - of course he disagrees. This made me uncomfortable and also made me question the car itself which he claims was in great shape. So I asked him to refund my deposit and that we no longer have a deal since he changed the price on me. He refused. This all happens in a span of 10 hours and he said his policy is to never refund a deposit even after 1 second of receiving it. Now I know why he wanted me to send him the deposit before he would send me the invoice. I called him asking to refund my deposit and he called me a "d**k". 

I have bought a lot of cars sight unseen and always had a very good experience except this one so wanted to let everyone know about this so no one else loses money to this guy.
