Well, yes, cars are heavier thanks to life saving crumple zones and other safety engineering. I'd rather crash in a prius than a classic mustang.
That said, its also a little unfair to compare a 4 door sedan to a 2 door sports car. Modern cars are still heavier, but the difference is a bit more sane.
I think my dad's Cadillac when I was growing up was over 5,000 lbs. The 70s and 80s certainly had heavy cars, but heavy and death-traps and super shitty mpg.
