Tires & junk in the trunk are the secrets.
I've been in spots where I was driving the Coupe & got a surprise snowstorm; nothing you can do but score a hotel room or give it a shot!
Now that I've got the wintermobile working & available I just leave the Xfires at home. No sense getting whacked by some other idiot out there.
Even though, Steve, I'd still have my hands glued to the wheel & be driving like an 80 yr. old bride: anxious but not sure just what the hell I'm doing.
