I have to agree w/ all above...I've had more comments from friends (without), asking why I'm spending so much on my 2 cuda's, and that I'll never get the cash back...maybe so, but I too, have found passion, and an excitement in my projects. My wife loves the fact I'm not bugging her all the time for attention. What comes to mind is:
New cuda project car...$10-30K
Restoring......another $10-40K
Driving down the road when complete(smiling at the critics)....PRICELESS!!!
Good Luck w/ your challenger
Cudaaah
