I checked the value of my '05 Limited roadster w/14,200 miles on KBB after reading this thread and I was pleasantly surprised.

Current private party value is $16.6K and dealer retail is $18.6K. I didn't look up trade in value because I'd never consider doing that unless someone was holding a gun to my head!

I paid $20.9K at Carmax in July 2008 and it had only 2,800 miles on the odo. I think it was a damn good buy for a practically brand new car that retailed brand new for $39K.
