Thinking about trading

I just purchased another new Journey 2013 with 3.6 , i had an 09 with the 3.5 .Was talking with one of the Mechanics there about the Dart and he said if you do not get the turbo , the other has very little power .I never drove one but thought i might trade my little 08 kia spectra but unsure now as the kia gives me 47 on the highway.
