I like the 2010 SX rims better. Think of it this way, if they only offered it on one model year for specific models, those parts just got really rare and worth more. In 20 years nostalgic Kia enthusiasts will give their left nut for a set of perfect 2010 SX rims.
I have the new 2011 SX wheels just like those and was thinking about selling them at some point. They are still on my ride with 1200 miles. I am actually headed to Florida (Central Florida) this Friday. Make me an offer and may think about it.
