Produced from 1965 to 1970, the side marker lights and taller windscreen with top-mounted rearview mirror mark this particular Datsun 1600 (née "Nissan Fairlady 1600") as a post-MVSS car, built between 1968 and 1970. We'll split the difference and guess it's a '69 model.
Yes, seeing this parked up on the side of the street in SoBro will cause me to pull to the curb, un-ass the Bimmer, and stand in the middle of the road taking pictures like a moron. This car just makes my heart go pitter-pat.
