TL;DR
LA autoshow is a waste of time and money...

well trained well informed models hoping you take their pictures... i have the internet. if i wanted pretty young things draped over cars id not wait to go to autoshow to get pics of it. so you wait patiently until they are out of the way and snap away like mad. they try strike up conversations and you shrug like you dont speak or understand english. thankfully GM had cutaway mockups of nearly every engine they make... all cars are rubbish now. all of them.
