it appears that you really wish to find the production year of that car. Well, I hope to help.
I33t9eek is correct about the pre 72 durant side mirrors. However, those mirrors were still allowed outside of the US after 72. Something about US requirements for larger mirror surface area demanded the new square ones for import. Just an item of note.
Assuming that the front 6JX15 fuchs are original to the car, the wheel finish indicates that they are not early deep wheels, but rather, the later shallow 6's. These changed mid production in 1971.
Soooo, with the help of the porsche sepia brown paint representative (Tim) , and the early wheel (and everything porsche really) guru Jim Schrager...I'm going with a 1971 911 coupe.
