Just to share some opinions as my wife bought a Savvy AMT half year ago, it's a 5 year car with 57k clocked in. After some debates betwen Myvi or Savvy, i realised she chose the correct choice...
Good
1) The handling is good.
2) Chasis is stiff for it's segment.
3) The AMT is a joy to play with, it's a robotised Magneti Marelli gearbox anyhow...
4) FC is low at RM0.10 per km.
5) Small compact easy parking & is a joy in city driving.
Bad
1) Engine is noisy.
2) Car unstable at highway speeds.
3) Crank sensor unit have problem. (My foreman says is common with Savvy)
4) Unpredictable gear change, AMT robotic change gear to "auto" and back to "manual" by itself. (Heard Elf Renaultmatic D3 synthetic gear oil can solve this,i will service her car this week try out)
Overall if you need a car from A to B, this i say is perfect, if you don't care about its looks, Savvy rocks in the small car segment!
