That car actually provoked nausea when I looked at the photos.

Regarding the automotive variation of the cobbler's shoes: back in the '70s there was a big frame shop in the Valley, guy did everyone's frame repairs.
I knew him from a mutual friend before I got into the car biz, and did a fair amount of business with him afterwards.
He drove a beat-up Chevy pickup to any business meeting or to give estimates off-site.
But at home - which was a large, nice property and house - he kept a lot of high-end cars for himself and his wife.
And he retired very well-off indeed.
Nobody's fool, he forecast how insurance companies would cripple the collision repair industry, and he was right.
