I recently bought Rtiz VDI. It certainly impressed me with the space inside. It is a small car with good pick up and mileage. The only downside is the noise inside the cabin - may be it is because of diesel. Otherwise it runs smooth and the following could help in the versions:
Cup holder next to the geat box - not in the door.
A little space to rest the foot on the clutch side
Integrated audio system in VDI
Alloy wheel and 185 tire options in VDI
Wheel mounted audio control in VDI. (surprisingly Zxi which is cheaper than VDI has it but not in VDI). Yeah diesel engine is more expensive but it will help on VDI, at least as on option.
