Only a few times since the I-9 I take to school is always packed and monitored closely. I've only done it on this 440 route and it does kick but in order to get that nice growl you need to hit 25+ quickly. Anything below, it's pretty silent. The back seats aren't much, mostly comfortable if you're like a little kid or girl. The trunk space is actually nice. The stock version which is why I got let me down, only because the head unit isn't anything special. I was expecting an aux cord but that's not in there. I tried playing music through the bluetooth but apparently it's only to make calls and contact onstar and such. I can take pictures later if you guys would like.
