if you are planning to change your 9 month old myvi for a new car, i would suggest you stick with the myvi for a few years.
you'll lose quite a bit of money selling the car now.

i believe the myvi has 3-4 years warranty, and if one service centre can't fix your problem, it's time to move on to another center.
as for the losses from selling the car, i think it should be closer to 10k with interest added in.
as for which car to get, remember CKD swift is expected this year.
if style is your top priority get the 206cc, if you want practicality, get the swift. Since you at it, why not look at the toyota yaris or honda jazz (even more practical)

hi trojan, i really suggest you try another SC
if one SC can't get the job done, there's no point trying over and over again.
for water leak, changing the carpet won't fix it problem, i believe there is a plug somewhere at the firewall, see if it has drop off.
as for the brakes, does your myvi comes with ABS. check the pedal free play and fluid level
