May I suggest a couple Minor additions to your Vehicle?
1- A Gatlin Gun, .50 Cal (you might need to put air shocks, and a bigger engine in the vehicle, to handle the excess weight of ammo......
2- A Rocket Launcher......
Seriously tho', back in 1980, I owned an Audi Fox on its last legs. One day driving home from work, a car had been tailgating me for a few miles, and would NOT pass, when He had the chance. I got fed up, put the gas pedal to the metal, and out came a billowing cloud of burned oil exhaust from hell. Had a Cop of seen me, I'd of never been able to get it smogged, without rebuilding the entire engine. A day or so later, the Fox seized up........it barely had any rings left....
I laughed the rest of the way home, cuz I never saw that car again, hell I couldn't see out the back window at all. Looked like a Southern Mosquito Fogger the way they leave a cloud of bug spray in the air, and it lingers for quit some time..
