- Hmm, just gotta clear up some misconceptions/typos/whatever...
- BTW: I'm responding about US Z's: Europe had a different lineup (no

- I dont believe there were any 260's with fuel injection. The 280Z came
- out in 75 with fuel injection (and a buncha extra pounds). If there was a
- `new' injection system, I'd assume it came out after 76, because 75 & 76
- share shop manuals. I'm also under the impression that the (rear)
- Chapman struts were used throughout the "Z" series: the trailing arm
- business appeared with the first "ZX" (79?) --- in any case, the 75, 76
- certainly have struts.

- Likewise, although I believe there was a slight blip when the 280Z
- (easily) recovered some performance over the 260Z -- but not quite back
- to the 240Z. It seems that there was a quasi-continuous evolution from
- "Sports car with GT aspirations" to a "GT car with sports car
- aspirations". The car generally got slower and cushier as time went on.
- Where the ideal point is depends on your tastes.

- I've never had any problems with my '75's injection system. The

- arms to cope with it. And that mileage is outrageous! I've gotten
- consistently 22-23 mpg in city/highway mix.
