Just bought a 2012 honda civic ex 40000 miles. Good deal?

So I guess I'm just looking for reassurance or some bad news. I just bought a certified pre owned 2012 Honda Civic ex sedan with 40,000 miles. It's white with dark interior, came with sunroof, Bluetooth and other extras like visors, mud flaps, premium alloy wheels, floor matts. No accidents, one owner and all services done at the dealer. Also came with 6 free oil changes. And as far as a warranty it came with honda verified 100,00mile 7 years, I had them add bumper to bumper 6 years for 7 bucks a month so long story short. Everything said and done its $200/72months, after $1500 down and $400 for trade in (surprised I got anything). Did I get a good deal?

Total cost $16,3000 I'd say that was a bit over the odds but not much - why such a long term?
