going from 185 to 215, you may need to change rims too

14.8km/l for full city driving? The 2005/6 city can definitely do 18-19km/l on highway at legal speed limit and i don't mean just from the trip computer reading but from refuelling calculation
If go by the trip computer, i've seen 25km/l at constant 80km/h for a distance of about 5km till i run into traffic
Prius is known to clock 3l/100km at constant 80kmk/h and number around 4l/100km is common for daily city commute

Would really love to see the diesel M2 here. Wouldn't mind paying 95k for it if equipped with 6 airbags

you car still new, don't think too much about the fuel consumption
too focused on that, later you cari pasal with your car instead of enjoying it

is that tar mark?
if it's tar, a stronger car shampoo should work
otherwise, can try tar and bug stain remover

RM310 for running number is crazy.
RM310 for a chosen number from the running series (meaning if now the series is ABC, and you want to choose any available number from the series), on the other hand, is the usual rate if you don't want to buy the number yourself and get a runner to do it for you. RM210 for the number, RM100 for the runner fees

of course, some sales advisor maybe be willing to do it for you for free but that is all dependent of the sales advisor
not all of them are willing to go to JPJ due to time and distance

alternatively, you can get a mySikap account and buy your number online
