I agree that this will vary greatly by each person.

In my case, the very high gas spikes last year really made me reevaluate some things. As crazy as it sounds, it was really something that made me think hard about why I am drivng roughly 110 miles each day to and from work. In addition, do I really need 2 cars. So after thinking it over, I will be moving this spring to have a reasonable commute and I am getting rid of both vehicles and getting the HCH. The money I'll save in gas/insurance/ and time not spent driving will be nice. While I always had thought that some day I would need to move closer to work, it all became clear last year.

Now all I have to do is wait for my car to come in.
