These Tan Chong SE are all liars.
Actually, i really sympathize with u and can understand why you are so upset. But why did u go back to them and buy a second car from them??
I've realised buying a car in Singapore is different from buying a car in other countries. Here, car prices are like the stock market coz it fluctuates up and down after every COE bidding... Almost impossible to buy at lowest price. If anyone can predict the prices, we dun need to work for a living liao.

So just LL, lor... Buy a car when u really need it and you think the price is acceptable. As they say, willing buyer, willing seller... Good luck!
