He’s not in the car business anymore but he used to rebuild wrecks all the time and some cars he had almost nothing into. He made good money doing it but got sick of working on cars.
A $300 Neon became a $3000 Neon after painting a bumper and putting a radiator in it.
$60 Olds was sold for $700 after putting a $60 starter in it.
There were several more he made tons of money on too.
Others were money pits though.
