Fun fact: there's only 770 millimeters between the taillights of a 510 (thanks, DatsunHistory.com!). To illustrate my point, here's another picture of the back of the car.
There seems to be one of those tree air fresheners hanging from the rear-view mirror. This was not a factory option in 1969, although some dealerships reportedly used air freshening technology to mask the scent of motor oil and deceit.
Oh shoot I already used this picture. Sorry about that - here's a completely different one.
I can't help but notice how evenly spaced this 510 is between the lines. Really, that's an A+ job. You probably couldn't get that in a BMW.
PhiLOL actually likes the tuna here, but abhors structural rust. Save the manuals.
