I've had my Soul+ for exactly 3 days, and I'm officially in love. This little car is comfortable, surprisingly spritely to drive, and very economical. We traded a 2002 Jeep Liberty, which is probably the polar opposite of a Kia. We gave up a tiny bit of cargo room and some horsepower. We gained state-of-the-art safety and a vehicle that is a joy to drive - so far. I realize it's early days. Something may go wrong, but right now I feel like this is not just a car, it's a large, gas sipping pet.
Front visibility, options, gas mileage, cargo space, overall design.
For what it is, I wouldn't suggest many improvements. A few more horsepower maybe. Homelink standard on all models.
