Don't forget the type where when you buy something they say "I know where you could have gotten a nicer one cheaper."
I remember when I got my silverado. This jackass laughed and said "Oh, you could have gotten one just like it for about $6500" or some price like that. I houded him on where. Well, I saw the truck he was talking about, it was 2 years older, with 20,000 more miles, 2 less cylinders and was a basic work truck edition probally off lease from a construction/utility company or something. I finally got back to him ready to put him in his place. He said "there wasn't much difference, you paid $6K more for the two tone paint, .5L more engine, and carpeted floormats and the miles you would have driven in a year."
I remember this one jackass telling me how I wasted my money on Snap-on because his harbor freight/husky/craftsman stuff worked "just as good".
There is a Jackass on this forum that when I was selling my camaro he said you can pick up Z28's just like mine for $2K, but I sold my car to carmax for $4K. He could not give one example of a car like this. He goes by stock90GT.
