Welcome aboard. You want the bad news or the good news first?

Uh, no. It's rusted as all hell. It's so weak, if you jacked up one corner, the doors won't open / close properly. That's bad. And the floor is, I guarantee, rusted. You just can't see it, because it's underneath a layer of rubberized undercoating (which seals in the water and rots from the inside out as well).
A good rule of thumb: The rust you can SEE is 1/3 - 1/4 of what REALLY exists. You're only seeing the outside of those channels, and they're completely eaten away.
An S13 doesn't have a "frame", it's a unibody car.
The rust damage I see in those videos is fatal. Period. You don't have to like it, but that car won't pass a state inspection. Any insurance company would total it, and you might have a problem insuring it. It's NOT driveable, and it won't be unless someone does 2 things:
* Puts it on a frame jig (to straighten it) - otherwise, you'll be buying tires twice a year, because the car will never roll straight
* Welds in a LOT of new metal (and not some half-a$$ job like the prior owner did - that mess is a joke)
Even then, it's a temporary fix at best. The suspension components attach directly to the unibody, and that car will twist like a wet rag if you take a curve or hit a bump. I'm guessing the mounting locations for the front suspension (up inside the strut towers) are rusted even worse. The first HARD turn, stop, or bump and you might be sitting in HALF a car.
That's why the shifter is all whack - the trans crossmember is probably bolted to dust and mud, not solid metal. Nothing you can do to fix that, unless you want to start over.
When you jacked it up, and it flexed, that tells you that the INSIDE of those channels (the "frame", as you called it) is deteriorating. Water gets inside there and the rust eats from the inside out.
(By the way, that's not the proper spot to jack up a 240 - you jack it up on the pinch welds - However, it won't matter. The structural integrity of that car is long gone.)
If you have the contact info for the prior owner (who should be punched in the throat), you may want to contact him and see if he'll take that turd back. NOT cool to sell something like that.
The good news: You're going to get a good education in taking apart a 240sx (which isn't a bad idea) - Because it's a parts car at best.
I've wrenched on (and restored) a lot of cars, and rust is the ONE thing that will make me walk away from ANY car. And I'm really, really good at what I do. This isn't a project you want to tackle, no matter how many people tell you otherwise.
$1500 doesn't buy a useful 240sx. I wish you had checked in before you plunked down your money, we could have helped.
Sorry to be the voice of reason, but someone's gotta say it.
