#1, Yes it's just Another Pussy Car. The sticker alone makes me want to punch this fucker in the throat, and the big R just means my Right foot up his Rectum.
The "R" stands for: "Hey Clint,'R'ya' gonna go ta' that goat fuckin' at Ronnie's trailer ta'night?" Nothing worse than a hillbilly that can't afford a '89 Civic hatchback to fix up, so he fixes up his S-10!
#5, Sure enough... it might even be a "Cheyene" (since it lacks the extra trim on a Silverado). It kinda looks like a Cheyene badge on the c-pillar too. Sorry!
