For sure the dodge truck.
I mean, its a freegin crew cab 4x4. In a racing game.
Otherwise, anything with " A Chevy 350!!" Is the ultimate redneck. So, Camero or firebirds, Monte Carlo from the 80s, (or better yet the standard buick regal or even better an olds cutlass with a vinyle top) chev truck, etc. "Small block chev!!" is the redneck battle cry. Because, any engine that can put out crazy power just by pooring more and more fuel into it is like the american redneck dream.
I knew a guy a few years ago at my last job that bought a 70's Nova. had a 350!! yeehaw right? it had an 850 cfm carb with big jets. The car had a 12 gallon fuel cell, and when he floored it from about 20mph, the car really took off. You could also WATCH THE FUEL GAUGE GO DOWN. Now thats some redneck engine tune right there.
I gotta say though, the GNX is no redneck ride. That was a real performer for its time. I wouldnt put the superbirds or old muscle cars in red neck row eighther.
There is a key aspect to redneck choice....it has to resemble a solid performing car, but it has to be very cheap. A well done Camero can even be a decent car, but a redneck wont tune a car. they will just "bolt on some chevy 350!!!" and throw caution to the wind. Brakes, tires, safety belts, suspension, etc are pointless compared to the 350. I live in NE Wisconsin, where about 30% of the population is redneck chevy fanatics, so I have seen it all here lol.
