If you talking about vehicles as part of your character or organization, I will say they will need some sort of justification as to why they do not appear commonly in the actual show. These may include:

- Secrecy

- Cost

- Private property

If you're talking about believablilty you might want to consult a mechanic or engineer. Then again, this is a show where bi-pedal mechs are a thing so do what you will.
