the idea of getting into a lesser car when the Z is sitting in my garage feels kinda like cheating on my girlfriend with an ugly girl.
I was thinking the same thing.

I am gonna rack up the miles, if I wanted to drive a beater every day, I would not have bothered buying the Z.

Really, when traffic is packed in and people suck (as they usually do) I could care less, I just take a deep breath and relax, I am in my cocoon. Besides, what are you saving it for, nothing last forever, you might as well use it.
