Should I trade my 2014 Nissan Maxima base for a 2011 Ford Mustang Base sports package?

It would be a even trade. The Mustang has the Mustang sports package with includes pipes, and a upgraded engine. Any suggestions. I would be trading a 2014 for something that is older, but better. My maxima has a sunroof, and power seats, and the Mustang doesn't.

It should probably be pointed out that *all* 2011-up Mustangs have dual exhaust even the base V6 model, it's standard, and the V6 performance package (I assume that's what you mean by "sports package") did have any engine upgrades. No offense but either you didn't do any real research about the Mustang, and/or someone is feeding you a line of BS about this car.
