they admitted mistake offer you full refund, just take lah. Why you want to take advantage of people's mistake?

Kena screwed once not enough? I'll take the money, belakang pusing lari kuat-kuat.
If buyer makes mistake, I wonder if the dealer forgives him and fully refund him.
Best advice, I'd do the same because I don't have the energy and resources to drag, not because I think it's supposed to be like this.
Unfortunately this is the reason they are free to take our deposits and not honour the deal for whatever reasons. No loss, only gains (selling to other buyer at higher price, or selling another car to the sohai who agrees to buy another car after they screwed him).
Exactly. Kena screwed and act steady. Some even suggested looking for another car from the same dealer, kek.

   
Tell it to those car dealers. Kindness goes both ways, not a one-way traffic. If the buyer makes the mistake and decided he cannot buy the car, tell the dealer to return him his deposit out of kindness and forgiveness, lah.
