Smack Talkin Chevy guy

Why are chevy guys like that? I go through this at work with a fellow mechanic." Why did you buy a damn Chrysler car?" he replies. He has a built 80 Camaro that he keeps breaking. Another mechanic is a Ford guy and has a 72 Grabber Maverick. He does not give me any grief about my car. He respects all makes like I do. If it's old and looks good, I like it.
