Personality! Not only do new cars all look the same, they are all FUGLY.
New cars are made of cheap, thin metal that bends if you lean on them, and when you get inside, you are surrounded by ugly cheap plastic.
You can have all the airbags, navigation systems, 4g LTE connectivity, back-up cameras, push button starts, and all of the other useless BLAH_BLAH_BLAH_BLAH that they cram into these overpriced tin cans.
Give me a 60's Impala, or Olds, or Pontiac, or mopar any day.
