Anyway like waht some of the guys have said, it really depends on your right foot and the road condition. I am a gentle driver. My best record was 13.5km/L on the highway from KL-Ipoh. But I know of one other bro who managed 14km/L. So, lots of variables involved.
Either Camry or Accord, you wont go wrong. These are the best selling passenger cars in US anyway
Buying a car you gotta like it. Can ask around for suggestions or read mags or forums. But, you have to decide what you want. This time round I find Accord suits my needs as well as for my family members who find Accord is the car to travel in amongst the few D segment cars that they have tried out together with me. Camry or Accord, you cannot go wrong with either of them. Accord commands the best used car price for the last 15 years in the US. Both are kings in the D segment category worldwide. Cheers.
