In the RM100-125k price range, you have many choices. In the end it will depend on what you are looking for a what is more important to you - the exterior looks, interior looks, interior quality, driving experience, NVH, resale value, aftermarket service and support etc.
Apart from the Nissan Sylphy and Honda Civic, you may want to explore Toyota Altis, Mazda 3, Peugeot 408T, Renault Fluence and Ford Focus.
FWIW I have owned the previous generation Sylphy 2.0. Not too sure how the current model compares with the previous generation model but if you want a quiet and comfortable car with smooth acceleration, the Sylphy is a good choice but performance and driving dynamics are lacking. Tan Chong's after-sales service is good if not great.
If you want resale value, Honda Civic and Toyota Altis would be good choices but to me they are overpriced for what they have to offer against other alternatives. Though there is no doubt about their resale. The current Civic is not as popular or well-received when compared to the previous generation Civic though (the previous generation Civic is thought to be the best model Honda had managed to come up with in terms design).
After-sales service and support of Japanese cars (Honda, Toyota and Nissan) are usually reliable when compared to the cheaper continentals. Mazda's support is a bit lacking but is improving.
If you want elevated driving experience compared to the Japanese cars you may want to look at the Ford Focus. But after-sales service is not as good as the Japanese, and resale value is also not as good.
i am .. impress thank you for word.. i will consider the choice you name except the Mazda3 as i feel look sporty to me(i understand most ppl interest in it's look, but way their site.. and lack so many way is kinda tell tale they don't care
) yes i am looking for Quiet, comfortable car with smooth acceleration (i got old mother to look after and once while i want her be very comfy when seat for long journey drive JB to KL IJN) hmm MEanwhile Civic /Toyota do have Great Resale value Yes i notice that when i did my First research
i saw their call still selling 60-70% original value after 5 year.. that is amazing... and why i added to my option of purchase.
