Though we had only about 45 people show up last Friday (I still think it’s because Jason and I drank too much the previous week, and our hosting skills dropped as a result), Jason and I had a great time chatting with readers about cars, and asking them these 40 questions:

  1. If a wheel has a 5x4.5 bolt pattern, what do the 5 and 4.5 represent?

Week Five Winners

  1. Team 7: 41
  2. Team 1: 37.5
  3. Team 5: 36
  4. Team 8: 33.5
  5. Team 2: 31
  6. Team 6: 22

Alarmingly, there were 51 points up for grabs, and team seven scored 80 percent of them! That’s quite a high score for a trivia night that’s meant to be rather difficult, though I knew week five would be easier than previous events, as I wrote the questions rather hastily. Still, the average was a 66 percent, so things weren’t that easy.
