I used to have a '78 Datsun 510, which was the 200SX's direct predecessor. It had that same weird 5-speed shift pattern. Can't tell you how many times I almost shifted into reverse instead of 5th!
It had the old 240Z engine and it was a scream off the line! The speedometer stopped at 120 (about 5:30 on the circular dial), but that needle could go nearly all the way straight down if you pushed it. I'm thinkin' 135 MPH, conservatively.
And it was still going that fast at 258,000 miles! Great little car.
