I love my Soul Plus. It's a blast to drive. It's comfortable. Great sound system and I'm getting between 39 and 41mpg.
I love the mood lighting and the CD player is smooth running with no funny sounds over the music. I love the large tail lights because no one can say they didn't see my turn signal. Everything about the car is just AWESOME!
In my opinion, there is nothing that needs improving. The car is just fine the way it is. The only suggestion I have is a wider variety of color choices. Other than that, it's a great car.
