I've driven a Soul 4u for the last 2 days while my Sportage is in the shop and came away impressed. Plenty of space all around, great standard features (heated seats, bluetooth, sat radio) and interior and powertrain did a reasonable job although it really could benefit from having a 5th gear... I really liked the higher seating position... about as high as a Rondo, between a regular car and a small SUV such as the Sportage.
A couple of things I didn't like: those rear pillars are absolutely huge and totally blocked my view when checking my blind spots for lane changes. This alone would probably stop me from buying this vehicle. Also, the car was just way too rough on bad roads. Either it's the suspension that was way too stiff, or it was because of the 19-20" tires. Another minor thing I didn't particularily like was the seat material... no where near the quality and durability of those in my Sportage. I felt as though my dog could claw her way through the cloth of the Soul in minutes while the seats in my Sportage look brand new after over 3 years of ownership...
Oh, and the LEDs in the speakers are just stupid and I turned it off after 5 minutes. Waste of money/effort IMO.
I'd be curious to try the 1.6L/manual and see how it fares... but as I said, those rear pillars would be dealbreakers to me. Hopefully Kia can bring over a Forte 5-door hatch with the 2.4L/6spd auto transmission... that would be a great vehicle!
