Does anyone have any experience with topacar.com.au

Hi all,

Just wanted to find whether this is legit. I sent an enquiry about a car that was on carsales and received an email from a team called topacar.com.au.

They basically don't have a yard where you can inspect the car. Instead, you pay a deposit of $50 and they bring the car to you. After the inspection they will refund the money. Also, if you like the car, you pay the total value of the vehicle, which will be held in an escrow account for 7 days in which period you can use the car. Basically test drive it for 7 days. If you don't like it, you can return the car within 7 days and get the money back.

Now, according to them, this is a new concept in Australia, which may be the reason why there aren't many reviews (none actually) about them. But does anyone of you guys have any experience with them?
