My coworker just got his last month and it is amazing. I love that all the aero and vents are actually functional unlike most Mustangs. It's a high-revving NA V-8 with that sound... omg, the sound...
This is the one Mustang that even haters have to respect as a phenomenal car. If they keep it to limited production, it should keep value really well. If you're only going to drive it on weekends, go for it. As a daily driver, though, be warned... it's thirsty!
