Terrific post.
It doesn't even matter about the value involved either, a guy with a P90 in SF at the company where I was working abused the hell out of it, at one point he tossed a big heavy tripod right on (not _in_) the trunk, didn't even blink.
That being said, you also have to have some perspective: I see exotics parked at the curb in NYC, because, well, it's a car, and the owner (presumably) enjoys owning and driving it and that requires using it like a car, that involves parking, driving in inclement weather, scraping curbs, getting scratches in the paint.
Honestly, if you can't handle that in some capacity, just buy something you won't worry about.
I can handle damage due to to the fact I am out on the road or if I mess up and cause any damage. It's the people that don't care/lack apathy( true better word than not respecting) about another persons car that piss me off. Why do people feel like they need to park next to my car when there are plenty of other spaces around me when I park in the middle of no where. Though I know people who feel the same way as I do will do that in order to protect both of our vehicles. But that is still a minority....
I know when I get the Camaro it will get scratches, etc. I know it will get salt on it because I will be driving it in the snow( I am not the type of person to spend $40K+ on a car just to park it 5 months out of the year, though do wish I could have a 2nd vehicle just when it does snow). It's the people who damage my car and don't give a **** about doing it that irk me.
