The Big Bang Theory: 15 Insane Details You Definitely Missed
1. Penny's Car Model Wouldn't Have A Check Engine Light
Throughout the Big Bang Theory, Penny's car constantly having its check engine light flickering became a semi-focal part of her character. Every scene in her car would typically see this brought up in conversation, particularly if she was travelling with Sheldon.
But Penny's car - her first one, anyway, which was a red 1980s Volkswagen Cabriolet MK1 convertible - wouldn't have a check engine light. Volkswagen vehicles from this era didn't come with a check engine light unless they had computerised engine controls, meaning that either it was another oversight from the writing department or Penny wasn't driving the car everyone thought she was.
Or, did Sheldon spot the wrong light?
Probably not.
