What's wrong with engineers now days?

I am more disapointed in the enineering its self. Take the 3.8 V-6 in my 2010 Jeep unlimited. What a shitbox and most other people who own one think so too. I have heard plenty of people who have under 50K talk about how it burns oil. Lifter tick when you start it up after it sits for a couple hours. I wont get started about the power.
my 2000 GC has the good old 4.0.

I've had people say to me "I didn't know that was a diesel" because of the way it sounds:banghead:
