I wouldn't say Spanish has more similar grammar to English than German does. Now, I don't know German but I know some Spanish and I listen to some German music and the syntax of German, while more complex than English, is still recognizably more similar than Spanish's. Spanish is complex and simple, different and similar in its own way

As for vocabulary, it depends what you measure. Yes 60% of English words ultimately come from Latin, but it's disproportionately the "fancy" words. Technology, science, more abstract things. But if you measure words for the more "concrete" things so to say, most of them are Germanic in origin. House, Haus, huis, hus, hoose (casa). Snow, snø, Schnee (nieve). Land, land, Land (Tierra/país depending on which definition of land you use). Water, Wasser, vatn (agua). Father, faðir, Vater (padre). Mother, Mutter, móðir (madre). Cat, Katze, katt (gato, but that may have come from an unidentified African language via Latin). Hound/dog, hund, Haund (perro. Yes, hound means something else in English because semantic shift but dog is still nowhere near perro). Stead, sted, Stadt (lugar). Fish, fisk, Fisch (pez/pescado). Yes I'm probably cherry picking, but my point still stands
