The '70 Impala was a real car made of large amounts of steel, etc. Similar to a Rolls Royce today. The new cars all just plastic garbage with more complicated technology to break after 2-3 years.
Yes I'm sure if you were to make a car today with the same amount of steel as 1970 Impala it would cost a lot more. Plus a 1970 Impala was hand made by union labor and not bolted together by robots and people who live the lives of robots.
OTOH people like their car's to have A/C, air bags, and get more then 12 MPG
Good lord man, virtually all cars made in 1970 had air conditioning, and certainly all full sized cars like an Impala. You speak from ignorance apparently.
Its also worth noting that a large, full frame car like a '70 Impala is much safer with normal 3-point safety belts than the modern cars are with airbags, simply due to mass.
