Yeah, used ones are a good deal. New ones can be a good deal too, especially in CO. I would probably buy new in CO instead of used. You could pay $1k more for a brand new car due to CO's $6k tax credit. This assumes you have enough tax burden to get the full federal and state credits. Last I saw Nissan was offering $5k cash back and 0% for 6 years on top. So it's $7.5k federal, $6k CO, and $5k Nissan off the purchase price. If you paid the same price I paid, you could get yours for $11k brand new (I got the S with the charging package).
