Take it offroad, get it muddy, and use it like a sport UTILITY vehicle, like it's designed.
Tear up the rear cargo area, with something dirty, maybe engine oil, etc.
Get some dents in it.
That will show that you use it as a man would. For utility and function.
It doesn't matter what you drive, it's how you drive it. If you keep it spotless, washed, keep all the trash out it...you're acting like a girl anyway.
Treat it rough, and use it as a tool, and you're acting like a guy.
And since the vehicle is a reflection of the driver...the vehicle will become masculine.
