I have signed "Contract to buy Motor Vehicle" with a dealer after negotiating the price and vehicle specifications for $32,500 and paid $1000 advance money, but now the car dealer says they cannot sell the vehicle to me and the dealer wants me to cancel the contract and sends my advance back. Since I already sold my existing vehicle and no car presently puts me in really bad situation. Since the signed car was 2014 with free rego and stamp duty and no other similar car not available with other dealers in Perth! Cancelling the contract and purchasing 2015 model would cost me additional $5,000 (approximate). I request your kind help and advice regarding my rights under Australian consumer law. Whether am I eligible to ask any compensation to my loss or alternatives to the dealer or enforce the contract? Does the "Sale contract letter" signed by both purchaser and Dealer Manager has any relevant legal value as it states?
