They came from the factory like that although the 2 door sedan is much rarer than the coupe in OZ.

I'd go for it myself - looks in excellent condition! ... I was brought up in a 120Y sedan and am still alive

Can't really talk though as we got a 2006 kia sedan with airbags / abs etc. for our family car as Mildman has suggested. It was either that or an N15 or N16 Pulsar for similar money, but we ended up with the newer Korean (and have been more than happy with it - although it's much less fun to drive than the 1200).
