Great to see you finally found the car you were looking for. I searched for ten years until I found my first custom sedan in '94. It was red and white just like the one in the original 57 custom series brochure that I bought at a swap meet when I was 14. I wanted that red and white custom bad and finally got it and a nice one to boot. Unfortunitly it was destoyed by head on with a drunk driver in '95. I survived with a few scars but my dream car ruined.Soon after, a friend gave me a lead on another red and white custom 45 miles away. That ended up being the black car which I have now. After checking the codes it ended up being an original black 312 car so that is way I decided to put it back. Ive been enjoying it for the last 13 years and love it. I continue to have a great time with it and hope I never have to let it get away.
I stil have the wrecked red and white car and have collected every part to build it again, but I am having to much fun with the black car. Maybe someday... At least I still have been able to hold on to it.
Good luck on your sedan and I hope it comes out the way you want and you get a ton of pleasure from it like I do mine.
It will be worth the wait when you start driving and working on it.
