Did I biy the wrong car?

I baught a 2009 scion xb 60,000 miles fully loaded nav., alloy wheels bluetooth all that good stuff. It Was $14980 final was 19000. It didn't have a warranty bc of miles. My dad did the talking my payments are 270 and he said that's great....but I'm second guessing it did I get suckered into a bad deal. My bf said my dad did horrible ...oh and bc I'm so young with no credit my apr is 16.....
