Re: What is the difference between a 280Z and a 28
The earlier Z's (240's and 260's) were built from '70 to '75, had dual carbs, few frills, manual rack and pinion steering, and a really good suspension made up of McPherson struts front and back. In '75 the 280 Z (not ZX) came out as a more refined (but still not luxurious), heavier, fuel-injected version of the Z.
In '79, the 280 ZX came out as a completely redesigned Z, with different body, suspension, and interior. It was heavier than the Z's, and got mixed reviews at the time. Also, in my opinion the ZX was the first 4-seater that looked anywhere close to right. My personal preference is for an '82 or '83 ZX, with analog dash and no climate control, but that's just me. I still want an enhanced 240 or 260 eventually for occasional road fun. The ZX's are heavier than the Z's, but for a daily driver they're my choice. Best suggestion is to go drive some of each, and decide which one you like.
