It is obviously a scam. What is the price of your car? Whats next the land is worth double the car and you have to pay them only 50% more? Plus you are going to have to pay stamp duty on the market price of the land.
Move on sell the car for cash. If its such a great piece of land you can always buy it with the cash you received from the car later couldn't you?
The price of the car is $80k+
Yeah, thats what I thoight. I could always buy a great piece of land with cash though she stated the benefit from it is that you get better value than purchasing it straight from the market but I doubt it.
