I've got a little 94 Pontiac Firefly I use for getting to the camp on the property and light yard work, it has not been inspected or taken to a garage for at least 5 years, and sat for 3 of those years, I've been changing oil and filters and fluids when needed though. The car devloped an issue just before the las fluid change and shakes quite violently when the engine revs up in gear. Put it in R, D, 1 or 2 andtry to go and the issue starts, leave it in Park or Nut. and rev the engine and no shaking occurs. (when rev'd)
To better outline the issue here's a quick video of the car and the issue.

I am thinking old gas or you need a new gas filter.

Wouldn't be old gas since the gas was bought the other day, but I've never changed the filter.
Hard to tell from the video but I suspewct transmission problem.
Gas filter is a cheap thing to change out.

I get one and see if it changes anything, While the car has never had old gas it has on occasion had gas with some dirt/derbies in it, for one of the red tanks you refill.
Have you checked your drive axles? It almost sounds like its broke or loose and flopping around when you try to drive. If you're using it off road, it could be something as simple as a stick wedged in there.
$100. bucks? ??? Not much you can fix for that. Maybe you could plant flowers in it.

I'll have to take a look under it tomarrow. Some could be broke stuck or lose I guess. It bottomed out fairly bad the other day (before the issue arose) so that could be a good thing to look at.

No, not much But I didn't pay much when got it a while ago. I could get another yard car for 100$ so I'm not willing to put much into this one. I just like this one due to how small it is making it a good car for the yard/property.

Yes it's a front wheel drive.
Torque converter bolts loose or broke? Drive line, u-joint or CV joint broke? Transmission shaft? More observation is necessary for a diagnosis.
Any attempt at movement when in gear or just the shaking and clanking?
I would suggest a helper putting it into gear and starting the issue with the brakes on and you observing to see where the noise comes from.
A pipe or tube held to your ear while in contact with the various engine or transmission parts with the noise going can help locate the problem. Use it as a stethoscope.
I didn't see movement in the video, but if it will move then have plugs and wires been checked?
