Fair, honest, personable. High integrity. Mr. Caldas is a man who, on principle, WILL NOT CHEAT YOU. His principles disallow it.
I've only been twice, but I'd say I've been engaged in probably 2+ hours of steady conversation with him and Mrs. Caldas and they are not shy to discuss their life philosophies. This is an upstanding man and garage. Period.
I don't know them well enough to say this, but I do believe it when I say that if I dropped a million dollar gemstone in their garage, complete with a price tag, and they found it (I don't know their staff but Mr. Caldas swears the most important thing in a new hire is trustworthiness in his books), I'd fully expect them to return it to me without even the thought of selling it.
Mr. Caldas actually drove me home when I left my car there. He offered this. Solid human beings here and I can testify from personal experience that they treat all races equally. If that matters to you.
