If I were to only care about performance, and nothing else then i would have gotten another ss. But for every day use I think this.
2 doors (unless I somehow found a clean sedan) vs 4 doors
Can't fit anything in trunk vs super easy hatch with lots of space
Plastic interior that rattles vs soft touch everything and solid no rattles
No warranty, higher mileage, possible "porous" block vs warranty and 20k miles
And also I've been in a cobalt forever lol so something new is just nice sometimes.
Also, I absolutely love the cobalt ss. For a performer it is hard to beat for the price, one day maybe I'll pick another up. But for me, right now.. the st is better.
