Obviously, people vary. I see a truck (at least, a clean city truck) and think, “Oh, man…bet that thing gets gas footage!” and know our priorities are probably too different for a good match. A work truck, battered and used? Probably different, but then I want to tread carefully and make sure we’re not going to have a conservative/liberal divide too great too cross. My SO had a battered Ford Somethingorother when we met; I gave him a chance anyway. 
Tattoos, I gots 'em. I like 'em. I especially like them when they’re a surprise - when they’re covered by work wear and revealed in casual settings. To me, that’s the perfect balance of Good Provider and Bad Boy. Yum! Adam Levine - perfect example. The man can wear a suit and you’d never know his skin was a work of art. But take off his shirt, and now he’s got stories to tell.
Really, just like the Woman thread, it’s all about the middle ground. No one likes too much makeup, but few truly prefer no makeup at all. No one likes too much muscle, but yeah, we’re not generally flocking after the underweight, either. No one likes too much perfume/cologne, but just a hint of good smell, bottle or natural, is a turn on. We don’t like braggers, but we’re not into terminally insecure, either.
And, of course, what we lust after isn’t necessarily what we end up taking to the altar, or even the bedroom. I drool over Bad Boys, but don’t get involved with them. I’ve dated plenty of Tortured Poets, 'cause I find them sexy as hell. I was wise enough not to marry any of them, despite several proposals. Adam Levine winds all my bobbins, but even were we alone together with a bottle of tequila…oh, who’m I kidding… Yeah, I’d do him in a hot second! But I don’t kid myself that we’d end up Happily Ever After.
Sexiness in either gender is about confidence and sincerity. Once you can fake those, you’re golden.
