current vios has much more discount compare to new model .
according to thailand price is increase around 3% , i'm sure that new model will not have discount when it launching. plus the increase price , price difference will have a almost 10k difference .
if not urgent to use car , maybe can wait till end year promo ? probably have some good deal later

probably around june

Design same as Thailand.

Today receive a flyer of Vios , discount 7500 for 2015 model only. If 10k discount i straight buy ady. House no second car, mom no car use and every morning i need to send her for work =.="

Just send your car to SC for checking. Mine having similar issue before, service center needs to dismantle the whole dashboard to check and fix. Based on the report, it's due to the airbag cable knocking to the dashboard.

That's what I'm worry also... but so far mine seemed OK. Depends on the skill level of the technician i think.

You should let others know which area you are from. Think most of the forumers here more than willing to suggest you a good SC at your area. 

Right now i'm getting averagely 13km/L. Using semi 10w-40. Eneos
I also have Liqui Moly Ceratec in my engine. You should try this combo.

Also, how do you calculate your FC? Vios 2012 doesn't hv FC dispay in cockpit.
So I pump full tank. Reset 000 on my mileage meter.
Drive until the almost empty or the empty signal blinks.
Fill in (preferably) at the same petrol pump. Take my KM readings and the Litre reading to fill up full (to the point the nozzle shut off by itself)
Divide the KM and litre to get the FC reading.

So you assume the petrol usage (litre) is what you pump earlier?
Then the KM reading is from distance set from 0?
Then you drive similar KM recorded on ODO?
Not too sure what u wrote. Just wanna clarify.
