Here's something you dont see every day.

Back in the seventies we had a customer with a similar set up. He drove a big Cadillac and could hop from his wheelchair to the driver's seat and fold the chair up and put it behind his seat. He pumped his own gas. We treated him like every other customer and didn't expect anything more. We could still pull his car in for service using the regular pedals but we all took a try with the hand controls.
