I guess in the end, it's your car... ...well, your parts... ...and you can do whatever you damned-well please.
For me it just seems like a waste to see that - I mean these cars are so rare, and in the eyes of most of the people on this forum, they're so priceless - so valuable, so appreciated, that we hate to see one effectively "dying."
My dad got rid of his 'Cuda back in 98. I wanted it, and at the time, he felt that I'd never be able to do anything with it - I was cruising down the road of a starving musician. Now things have changed, and I'm slowly bringing my own Mopar back to a life of respect and muscle.
I guess I dunno where I'm going with this, but I just think that if you know you're going to leave a classic car sitting around to fall apart or rust to nothing, why not sell it or donate it or something - give it a chance to live again.
Lord knows the days of high powered gasoline-fueled engines are quickly coming to an end. Soon we'll be retrofitting our muscle cars with hydrogen fuel cells and whirring off into the horizon... Yippee...
