The Dart was marketed as a BIG compact. Buy todays standereds it is a midsize car. It weighs less than a VETT!!! What more do you want?
I don;t want anything. I am just saying that you can't compare apples and oranges. It is rediculous to try and compare a dart from the 1960's-1970's to a car that was made in 2005-2008. Heck you can't even compare them to a 90's car. Its silly to do that. Who cares about wheight and horse power comparison. You say that the dart is lighter than these cars... But the dart doesn't have The bigger rear end as these newer Posi driven cars. They don't have all the electronics, Airbags, Speeker system.
If dodge was to remake the dart today you would either get a car that looks like a Yaris because it is keeping the dart as a compact that it was befor. Or you would only be able to get a 4 dr model sedan...Which I am sure would out weight its current compitition in GVW.
All I am saying is it is uncomparable.
