My girlfriend's sister has a Mustang. Not macho. At all. And an RX-8 is just about as far from manly as you can get before hitting Scion territory (which, admittedly, is more douche than girly, but still).
I sometimes get to drive an 1986 Audi 100 1.8 with LPG and exhaust pipe completely broken off near the header. People run away in shame after hearing the sound of this fine piece of flawless German engineering. Timing and mixture are set just right for the engine to spit massive fireballs from underneath the car, reminding others of the pure awesomeness and manliness of said vehicle. That thing is macho as hell, and has some awesome features like shift into neutral to hear what your passenger is saying and shift back in gear to shut them up or depress the clutch and gently push accelerator to remind bypassers who is the boss of the street. The car is perfect, and has not a single bad thing about it. Well maybe except shutting down in the middle of an intersection and refusing to ever start again, making you push it back home. F**k that. But even when pushing that machine you look as manly as it's possible to look, as there's no thing more manly than pushing a 1500kg piece of metal with a single hand and singing a song simultaneously. Image of said vehicle attached below.
One of the more subtle (in that the impossibility is never alluded to) jokes in Spongebob is that there's a beach when they all live underwater anyway. It looks like someone actually found one.
