I found a web site called "Bring aTrailer", The Roosevelt 1957 Porsche Speedster Racer Accident Basketcase
there are a lot of posts on this site regarding this car. Based on what I read, no, it isn't worth 47K...
Eh, you could probably trade them some spare 1911 parts for that...
I've been around cars since I was born. Started working in a body shop at 16 and still here today. We just painted an '84 911 all over and it'll be leaving today so it's funny you posted that. I'm not a Porsche guy so I wouldn't give a $100 for any Porsche.
