Wow. I drive the piss out of my car on logging roads. I cut and drill the interior plastic as I see fit. I've got a set of rubber floor mats, not because I don't want the RS ones to get dirty, because I don't want the floors getting mildewy from all of the water and mud I track in.
Do I love my car? Yeah. It's awesome. But it's just a car. No need to stress. Same with that Jeep I'm trying to sell. It was a $35k Jeep... I took it wheeling, over the axles in mud. I loaded dogs in the back, I've taken a couple of loads to the dump, I've hauled lumber around in it. Even if it costs an arm and a leg, it's just a car. I clean it out and it looks great. But I've lost my urge to feel anal about protecting them.
