How about the people who ignore the red blinking/buzzing light on the dash? I've had the pleasure of replacing a few engines because someone ignored that annoying flashing red light on the instrument cluster.
Take, for example, the lady who "ran off road and car bottomed out, drove another 1/4th mile then shut engine off", well, I'm going to be putting the new engine in starting tomarrow. About 30% of the oil pan was missing, and even before I unbolted the oil pan, I could see babit oozing out of the main bearings.
Or the "cust states oil light warning has been coming on for the last 3 weeks". Not only did I put in the oil pump, I got to explain the workings of a turbo and why they now need a new one for that Passat.
And just last week I got to put in a set of rings since the water pump failed thus all the coolant was pumped onto the pavement and the driver kept on going.... for a couple of days. Super low compression in cyclinder #1 and #2, but the head and block wasn't warped at all, surprised me.
I think all of these people have "Black Knight Syndrome". I'll bite your legs off!
