Hi,
Don't think many workshop in S'pore will keep much accessories on the Kemara cos of price competition in M'sia. Believe M'sia is still the best place to go.
Anyway, I was at McWell Ventures (Paya Ubi) last week and saw a S'pore plate Kembara (looks like a M'sian car but its reg in S'pore). When the mechanic jam the accelerator, can really hear it roar! Was quite taken aback cos its suppose to be a 1.3l jeep rite, but it sure sounds like 1.6l or more! I'm sure this Kembara can makan my Civic anytime.
Maybe you can take a look at Paya Ubi or JB, I'm sure if you throw 1 to 2 k singapore dollars there, your car will come out differently! But of cos, pls do be careful when you go to JB workshop, its best to get some recommendation ard.
