Just out of interest I noticed the post from 'boyblunda'-
"Before the issue arises again, there was a new 260Z model in 1976 starting from RS30 015001"
This intrigued me so I checked and I have RS30 015011 built 10/1976 (Red 110, manual) and sold June 1977, Victoria.
Someone mentioned in an earlier forum regarding late model 260Z's that they had read somewhere that only 96 '77 260Z Coupe's were brought in for the Oz market?
Recently I was looking at photo's of a 03/1978 build UK 260Z and noticed that it had the older 260 (74-76) 'flat' horn pad which was a bit unusual as all of the other 77/78 original 260's (and 280's) I have seen have the newer 'deep' horn pad. This UK car had been put away by a collector for the past 27 years and only had approx. 8,500 miles on the clock and was passed in at auction...if I remember correctly they were after 26,000 Pounds Stirling for the car. Lot's of underbody component(s) 'surface' rust as well as some in and around the engine bay, but 'appears' to be a very original undamaged/unmolested car.
