I would use it to buy admin on FSE
I'd also buy myself some friends and have a regiment with a fully integrated payment through paypal so people are actually payed semi accurate soldier's pay of the era. In this way, I get loyalty and large amounts of people.
In all seriousness, I'd buy myself a garage of these badboys
"Sesto Elemento"- Sixth Element
and for the regular commute
I'd also unban all those who were wrongfully banned
