Before I even begin reading, I can see that there is a formatting error. It may be because of the way your picture is oriented, but the text after the bold headings should not be below the actual heading. Also, you should note that numbers are not reserved, so you are not guaranteed to have the number 2973.
SCP-2793 is to be stored in the Secure Vehicles Storage Facility in Site-██
Just, like, wherever? Should we park it in the lot? Crash it into the break room?
where access is restricted unless accompanied by Level 3 personnel or higher.
Why? Restricted in what way?
a state of severe rust and repair.
"State of disrepair" is what I think you were trying to say. Though not incorrect grammatically, "a state of rust" or "a state of repair", are awkwardly-phrased. I also don't think anyone would describe a rusty old car as "repaired".
start to mobilize
Mobilize what? Did you mean "start to move"?
even though the wheels are removed and no engine is present
Why is that?
an interaction
Like what?
even though no engine is present
You said this already. I would delete the redundancy.
charge at
Off-tone and not the best word to describe a machine. "Charging" is generally used to refer to animal behavior.
open it's hood
its*
attempt to devour
Off-tone. How? Does it like prop itself up or something? I thought it didn't have wheels?
the subject
What subject? You never mentioned any experimentation previously.
resume mobilizing
Mobilizing what? Is it just constantly preparing itself to move? Why?
No remains of victims are seen after the attack
The tense of this sentence makes me think that the "victims" are Foundation personnel. Why would they go near it if it eats people?
an oil stain
Where? From what? I thought it didn't have an engine? Is it a ghost engine?
SCP-2793 is held in the Secure Vehicles Storage Facility in Site-██
You already told us this in the containment procedures.
4 50-watt spotlights are shone directly at SCP-2793 to restrict movement.
This should be in the containment procedures.
witnesses report
reported*
to cover up
Not entirely off-tone, but I've never been a fan of it and there are better ways to say this.
