Maybe a few new ones: you love shutting down a warm truck in a busy parking lot to hear the loud squeak and chirp, and all the weird looks; you so badly want to get home from work to drive your truck, you actually want to vomit. you take better care, detailing and cleaning, armor-all-ing the rubber and plastic parts of the motor than you do the exterior. it isnt out of the question to wear an earplug in the right ear on a long trip to lessen the headache from the drone/turbo whistle whine. Enjoy pulling up to the K1 pump, and pump away, just to see the looks you get from "uneducated" drivers. Bring up in general conversation about how you're looking for waste motor oil, to lessen costs, and "help the environment". Finally: anyone who has never rolled down their windows in a tunnel or near a wall, angled their mirror to see smoke, or rolled their window down as they see a 2500 or 3500 coming to hear the motor, only to be dissapointed when it is a stupid HEMI is FLAT OUT lying.
