Numbers don't always tell the whole story. That is more or less why I suggested the OP test drive it. The SkyActive Mazdas (13/14+) are completely different animals then the previous generation. The previous gen you were 1000% Correct. Nothing wrong with the older 3's, they are just a little more towards appliance than the new ones. The on/off partnership between Ford and Mazda is gone for good. They ended that in order to "team up/tech share" with Alpha/Fiat on the 4C and new miata roadster.
The Optima is great. My dad has the loaded model before you get to the Turbo Engine. I will say he has had a couple issues he's needed to bring the car in for, those were rather minor issues though. Sun Roof 2-3 times, and HVAC once.
Edit:
Yeah...... there's no room in those vehicles lol. This is coming from someone who drives a 2 Seater, and lives in a 1000 sq/ft house. I know living small.... and the versa is small lol.Versa has tons of room?
