Just wait and see - COE has very limited upside due to huge supply.
The demand is going to be muted as population growth has stagnanted, 50% downpayment, better public transport ( more buses, MRT less crowded, downtown line running), slowing economy, coming sibor rate hiking to 1% by end of 2015.

Just sold my 5 year old for 60k car and take profit of 10k, haha
Thanks to the car salesman who keep spreading fear in the forum of COE price going up, many gullible people around
