I do indeed mean a stable! I don't imagine the particulates coming out of stables are going to be all that great. Also, my car doesn't get sick if I park it next to somebody's beater.
There are classes of parking garages too. I’m not parking my hypothetical dream Ferrari next to some poor person’s beat up Honda civic from the 90’s to get dinged and the windows broken. The underground parking garage at Apple must be astounding.
