I had a '78 Toyota Corolla that weighed 1900lbs, had NO safety equipment other than seat belts and belted out about 70hp. It got about 45mpg on the highway.
The new Jetta weighs about 3000lbs, has 6 airbags, anti-lock disk brakes, a very safe chassis and has 100hp. It gets a little better mileage but is much quicker and WAY more comfortable. Of course I paid $4k for the Corolla and $26k for the Jetta...
