isn't Spanish some form of Latin (being colonized by Rome for centuries), what I would be interested in, if there are some Vandal leftovers in nowadays Spanish

sorry, it was the Visigoths, not the Vandals

Guerra, perro, more that I can't remember, and a good chunk of names (in Spanish):

Well, let's see:

Perro, guerra, mes, pagar, ver, fuego, tierra, cima, perro, clero, altar, tribunal, rey... lots more. Tapa, dardo, ganso, ropa, guardia, sala, cama, barro, guijarro, zarza... more than anyone would think. Aspa, espía, brotar... and the -engo suffix. Visicothic and Celtic cultures are more ingrained in the North/Middle of Spain more than anyone would think despite everyone pictured it as a 100% Mediterranean culture.

Rico/rich, fresco/fresh, Blanco/blank, ganar/win... is not a coincidence.

Heck, tons of Medieval lore in the Castilles use a Gothic typeface...

Engo/enco suffix in words, related to -ingos in Gothic.

On names and surnames... Alonso, Alfonso, Guillermo, Fernando, Hernando, Hernández, López, -everything ending with -ez-, Leovigildo, Rodrigo and tons more.
