As much as i want to sympathise with you, I cant. If i put myself as the dealer I would never refund you back regardless of whether i have gone ahead with ordering the car or not. Why put a deposit down in the first place, the whole purpose of deposit is more or less like an agreement between two parties. Youve paid so he doesnt sell the car to someone else or in the case of a new car you are paying a deposit giving them the go ahead to continue with the order etc. This is time wasting as well and time = money. Furthermore, I had someone do this to me when they wanted to buy my car. Infact it happened to me twice and the first time i felt really hurt by the actions of the potential buyer. He test drove the car, come to see it three times, wasted my time, loved the car and with no reason backed out of a deal. The second time i took a deposit of 300 pounds and the dude did a similar thing. I refused to give him his monmey back, he made may threat which i laughed off and to be hoenst was 300 pounds better off as luckily a week and a half later someone else bought the car.
Likewise i dont know where you stand legally but i wouldnt return the money.
Sorry if i come across a little abrupt but i hope you understand where im coming rom
