Hi caj, Welcome to the forum.
On question number 1, I'm old school too. I really can't tell the difference on the sound systems except the 368 watt would be louder.
2, I have a Grand Caravan with a donut spare. 2 flat tires later I bought a full size spare put in back of the van. ON I-94 doing 55 mph doesn't cut it.
3, I just recieved a Garvin GPS for B-day gift from my kids works great ($250). Mounts on top of dash. My daughter has a My Gig unit in her Jeep. It doesn't works because there's joystick with it that doesn't work. New models don't have the joystick. Thirteen hundred to replace.
4, I can do without that, but do they really cover anything. You gotta read the "fine print" on the contract.
Finally color, SILVER is the fastest. Cheers
P.S. I'm not saying don't get a spare tire. I'm saying get a full size spare tire. A Challenger should not be seen limping along doing 55.
