Don,
Maybe it was a car before I got it, maybe it was a car the first time I pulled it into my garage. But after the hours spent bringing my 78 Targa back to life, the hours spent on the most minor part... well, I guess I don't consider "it" a car anymore. My time spent is what I don't want to loose.
But I do offer my wife the keys whenever she wants them. She took me up on it once but for some odd reason has this idea that it would be really bad to damage the Porsche in any way. Why? Because she respects and values my time spend rebuilding it I think as much as I do.
And it is that, that very last point why I will always give her the keys. She understands.
Hmmm.....Of course she might be jumpy because I yelled at her for pegging the tach the first time she started it!

Hehe. Still not "just a car" though!
