Chicken man

Hi, I'm pretty new to the car scene and have yet to buy my first car and then wait two years to drive it but I've narrowed the choices down. I'm either going to pick the Datsun 240z or the 280z but don't have my mind straight on either one yet. I plan on buying one in fair condition and rebuilding the engine with an older friend who owns a 300zx and swapping everything out for more current models to ensure driving quality. But what are the pro's and con's of each car. I've heard the the 280 is heavier while the 240 is lighter and smoother to drive. Just give me a big pros and cons list of each car while being realistic, thanks.

Hey, just wanted to introduce myself to everybody in the forum here. I joined because I'm interested in buying a Datsun 240z, or the 280. I'm not old enough to drive a car yet but have joined because I've heard that Z forums are full of friendly people. Anyways, that's pretty much it.
