What a pleasant surprise to find this thread here.
I have not read all posts so forgive me if I am repeating others' comments.
First of, it would be wise to keep the car cosmetically and technically original just for the simple reason of resale value.
As market tendencies go your best return/resale value would be Europe, especially Germany.
The car could however never (or should I say near impossible or only under serious time investment and red tape battles with German bureaucrat Red Tape) register the car.
Having said that, of course the car can be built any which way,for fun, but it could just not be permanently
registered as a "H plate" (meaning historical use and original configuration specifications....)
But I am sure you knew all that.
To build for fun , the sky is the limit here in the US.
I would however suggest that the body would be restored stock and a mild modification would be practical and possibly reversible.
As for paint color.
Again original would keep the value of the car high.
If you need help with original dartacard/ specifications and/or color code I could possibly be of assistance, if you need it.
Looks like a great project,if you can get it going....
Arguably that 220 is more complete than my 170.
See, I couldn't bring myself to tear apart one of these to give life to another if I know both could live.
I have no attachments to a Nissan, so ripping parts out of one won't hurt me one bit.
Taking from another Benz that under the right care could have a second shot at life makes me want to cry.
It's like you're speaking from my soul.
I have dozens of Mercedes, but no 170.
I have to warn you, it gets miserable if you try to save them all........(ask me how I know)
