Well, you see, this is actually a "problem" for me too. Right now, between my wife and I, we have the VX and that's it. I want to keep the VX as a collector car and buy something more "green" to commute in. But when it comes down to it, I am faced with the following problems:
1) Within the next few months, I should be the proud owner of my "other" dream car, a XB Ford Falcon Coupe. As for gas consumption, I better stop thinking about it and just deal.
2) My wife wants a car. You know what she wants? A Porsche 928 or 968. Not exactly green either, or at best, not cheap to maintain. Of course, it would be nice if she wanted a practicle commuter car, but I can't blame her when she says, "why can't I have a cool car too". So, if things go right, I will have a fleet of black vehicles consisting of my beloved VX, a black on black Falcon "Interceptor" and a shiny black Porsche 928 or 968. Two people, 3 cars. At this point a practical commuter car will be a moot point.
3) And oh yeah, I shouldn't forget about my black 2000 Xterra that is still sitting in storage with a blown motor in Chicago...

EDIT: PS - You only live once, why drive a Tercel when you can drive a VX? (or a Porsche or a Falcon?)
