Just ask yourself if you think the picture looks good. If the answer is no, you stay away. If the answer is yes, you make sure all the functions work well (make sure the zoom works well, make sure itfocuses at all focal lengths on YOUR camera body at various distances, make sure the aperture blades are snappy and free of grease, make sure there is no fungus growth inside). Personally, I wouldn't purchase anything if I cannot test it out. A seemingly good deal is not worth the headache of possibly getting a bad copy of a lens.
If you want to get into specifics for these pictures, they lack contrast even though according to the exif, the contrast level is set to "hard". Also when the picture is taken against a bright light source, there is flare and further loss of contrast. Could be because of fungus, scratches, lack of a hood, or a number of other things.
Also, you have to keep in mind that this guy is trying to sell you this lens. When you try to sell a lens, you show good photos to inspire the buyer. The guy's white balance is off and composition is terrible. If that's what he shows to sell a product, he either doesn't know how to handle a camera or he just doesn't care about the sale. Either way, do you want to make a purchase from someone like that?
I've seen the 35-70 2.8D deliver some stunning photos, but these sample shots are far from what you would expect from a (retired) pro lens.
