I did have an opportunity to visit Greg at his home about five years ago, stayed overnight, shared food and drink.
As I recall, his former wife still lived in the area, and they were on good terms.
Besides his stellar mechanical knowledge and skills, he was well read and articulate. You sensed that immediately when you spoke with him. He had no need to adopt a phoney accent or manner of speaking, like some others. He was also fluent in Spanish. He was what he was, and had no need to put on an image. I was also aware that his body had taken a beating, joints, feet, and such. and he was in some pain, but he didn't complain.
Vaya con dios, amigo. RIP.
Paul
