It is a very well designed car with some quirks. The herky-jerky transmission goes away after you get used to what it wants to do versus what you want it to do and understand how to take control. There have been some teething problems as can be expected with a totally newly designed car. That does not take away from the fun of driving it and the savings in gasoline that goes along with it.
It is fun to drive, gets great gas mileage and favorable pricing.
Cruise Control, Cruise Control and Cruise Control (hopefully as an add-on accessory for those of us who already have the car). And smooth out the transmission shifting.
