Hey Bill,
There is only one true cure in my book.
After I reluctantly parted with my first Cobra that I planned to keep, it was a very short amount of time before I was right back on the phone (while not working and out of contracts at the time) ordering the chassis and body for number two. Working on friends or customer's cars does not help as a remedy. There is only one cure.
For some, strangely enough these Cobras actually become part of who and what we are, and certainly contribute to my happiness on a regular basis. I've owned and built exactly 104 personal-use cars and motorcycles in my life so far, and nothing compares to the Cobra for me - not even close. Man, I want to build a GT40 so bad, but I just cant let go of the Cobra to do it.
I know what you are feeling. Fill that hole! Call Peter today and order yours to build and keep, and never look back. Good Luck.
