"original color not known". hmm. Seems a Certificate of Authenticity from Porsche could help here. Or looking for the color code panel (assuming not removed or painted over).
Windshield "seal needs to be replaced, but doesn't leak".. sure... doesn't leak till it gets wet
3.2 or 2.7, No title? really? How about going down to RI DMV and getting a replacement title, no? Mirrors are wrong for the car.
This car sounds like a hot mess. Sounds like someone trying to cash in on the "Carrera" price rush. $25-35K for a US spec, non numbers matching, repainted, no title 911 that was not much more than a trim package in 1975?
