Did I get a good deal on this Civic?

I've been looking all over Long Island, NY for a 2010 Civic. I had a 2001 Civic 5 speed that was great, but the traffic on a 2 hour commute (total) each day is killing me with the clutch and shifting.

I had been looking all over for something decent in the 2010 year, no frills (LX is what I wanted).

I found a 2011 Certified LX with 6k miles on it and I got it for $16.5k + tax.

I know it's after the fact, but did I get a good deal, or could I have gotten better? I'm honestly just curious since I know zilch about cars.
