A salad of despair

Yet at least he had believed in the cars, maybe to excess: how could he not, seeing people poorer than him come in, Negro, Mexican, cracker, a parade seven days a week, bring with them the most godawful of trade-ins: motorized, metal extensions of themselves, of their families and what their whole lives must be like, out there so naked for anybody, a stranger like himself, to look at, frame cockeyed, rusty underneath, fender repainted in a shade just off enough to depress the value, if not Mucho himself, inside smelling hopelessly of children, of supermarket booze, two, sometimes three generations of cigarette smokers, or only of dust — and when the cars were swept out you had to look at the actual residue of these lives, and there was no way of telling what things had been truly refused (when so little he supposed came by that out of fear most of it had to be taken and kept) and what had simply (perhaps tragically) been lost: clipped coupons promising savings of 5 or 10c, trading stamps, pink flyers advertising specials at the market, butts, tooth-shy combs, help-wanted ads, Yellow Pages torn from the phone book, rags of old underwear or dresses that already were period costumes, for wiping your own breath off the inside of a windshield with so you could see whatever it was, a movie, a woman or car you coveted, a cop who might pull you over just for drill, all the bits and pieces coated uniformly, like a salad of despair, in a grey dressing of ash, condensed exhaust, dust, body wastes — it made him sick to look, but he had to look. If it had been an outright junkyard, probably he could have stuck things out, made a career: the violence that had caused each wreck being infrequent enough, far enough away from him, to be miraculous, as each death, up till the moment of our own, is miraculous. But the endless rituals of trade-in, week after week, never got as far as violence or blood, and so were too plausible for the impressionable Mucho to take for long. Even if enough exposure to the unvarying grey sickness had somehow managed to immunize him, he could still never accept the way each owner, each shadow, filed in only to exchange a dented, malfunctioning version of himself for another, just as futureless, automotive projection of somebody else's life. As if it were the most natural thing. To Mucho it was horrible. Endless, convoluted incest.

The life of a used car salesman sounds terrible.
