I took a taxi home from work, and discovered that my car is still sitting in my house parking space. I called the Chrysler dealer, and was informed that some kind of mix-up occurred, and no one was sent to get the car.
Kind of bummed about this, but it's too late in the day to do anything about it, and will have to work something else out in this regard. Waiting for the garage to call back and let me know what's going to be done about this. Probably won't hear back from the garage until some time tomorrow morning, but I can't keep driving around in this weather with snow tires! (And of course, I don't have my car keys since they're with the dealership!)
