Lots of good examples but if the mind is made up there is not much you can do
 
if it is the old consumer reports mindset then tell him not to drive 55mph and cranked the wheel as it will not end well - in any truck or car

I have a lifted 4dr and I drive it anywhere and on any terrain with no issues of stability or concern

I was doing donuts and my father got upset as he thought I would flip but I never felt that it would - Dads

Good luck and the best way to change a mind is to take a ride in one

just out of curiosity what model and where and what is the price?

Sorry, but with a comment like that, I doubt you will ever change his opinion on this. I would bet he is a Chevy, Ford or Dodge guy that only drives full size vehicles. Fact is, they are safe for what they are, but put either of my Kicks up against my Suburban and it is toast.... any smaller vehicle would be being tagged by a vehicle double it's mass...

If he's going on the old Consumer Ripoffs Reports.... you probably wont change his mind either.. people live by what those DA's say about products.. 

Tell him to by a 70's Buick 225.... low, heavy, full frame and will crush most any thing they hit....
