So buy 40 humvees a box truck with a winch, create a shell company, hire 5 cubans, mark 12 hummers 1,2,3,1,2,3,1,2,3,1,2,3 only rent out 1,2,3 at a time, while the cubans keep the other 9 running, pulling them back to the top secret base in the box truck. Corner the market on 6.2 and 6.5 parts.
Your competitors will see that your 3 hummers are always rented out, with no downtime and want some for themselves. Start selling them hummers from your shell company, taking their Jeeps, utvs, or whatever else they might rent out on trade.
Then as they're failing and grasping at straws, on a hectic Friday afternoon, drop each of your competitors an offer on your 3 hummers, 1,2,3 and unload them 12 lemons right then
Bankrupt them fuckers, takeover their real estate then rent out their Jeeps and utvs
On their way out of town, tell them about the cubans
