Welcome to the forum.  And thank goodness said apprentice crashed it on the current owners time/hassle, not yours.  Hope the next one is just the ticket, just keep it away from apprentices.     
  
  
 
Sounds like one to walk away from, good a escape.   
  
You do hear of the occasional one with condensation on the headlights, less frequently the taillights.  Would make you wonder where it's been, given it's getting a bit warmer over there now.   Are you definitely sure it's on the inside??  350's can suffer from oxidation of the headlights, making them look very hazy.
