Alright, first of all, we don't use language like that on our "family friendly forum." There are lots of good alternatives such as irritated, ticked off, mad, etc. It reflects more positively on yourself if your vocabulary consists of more than 4 letter words (or "-ed" variations).

Now to the issue at hand, the weight is a common complaint, the thing you have to understand when comparing the current Challenger to the classic is that people are demanding that cars are made to be as safe as possible while being as affordable as possible. Now we not only have the Gov't cash tests but insurance companies crash tests. If the manufactures want to be able to pass all of these test, they have to build up the structure. The potential danger they run into if they don't increase the safety to perfection level standards is lawsuits. The fact of the matter is even if someone is doing something absent minded with a car and get themselves killed in the process, many greedy family members then want to blame the car company for the compact not being able to withstand having a head-on collision with a semi with a combined speed of well over 120mph. There are ways of doing this that will not way as much; however, the problem is these routes really cost quite a bit of money and on top of this some of them are still questionable on if it is really as structurally sound. That is why it weighs so much.

Another point to help you feel better about the situation. Thanks to improvements in transmissions, engine's efficiencies, much better tires, and other improvements that have come out since the 70s, these cars despite being heavier and producing in some cases less tq & hp, they are still faster than their 70s counterparts.
