Its not a Colonial thing or a SL specific thing....I don't think the Mazda 6 2.0L comes with i-eloop in any market (and I believe only a few markets actually have a 2.0L Mazda 6). I know it doesn't in SG and Vietnam...but then on the other hand the Vietnam market "Mazda 3 15-Deluxe" does have i-eloop (which in Japan is not available on the Axela because it wasn't efficient...so go figure).
Also, in typical Japanese fashion, what they offer for themselves in the local market is most of the time quite different to what they would offer to the export market even if it is the same product.
As for the Premio (and Allion)...it is sad how our car importers (being the "car pundits" that they are), are still peddling what is essentially a 10 year old car with a few shinier bits and features from this decade stuck in when and where possible. Its as pathetic as a pimp trying to find tricks for a 70yr old lady of the night. Would be interesting to see what the TNGA based Premio/Allion would be like.
