Season 1 episode 4 when Newton Pulsifer is in his car to go see Agnes Nutter, you can briefly see the reflection of a crew members face in the car window.
At the very beginning, when Crowley's car explodes, he laments, "Ninety years and not a scratch!" Except earlier that week he hit Anathema Device while she was riding her bike, denting the fender and breaking the headlight. He repaired the car through magic, but it was definitely not pristine before he did so.
