Not to say I demand alot or condamning you, the chart is good, but don't know when is this chart made. But if follow number 0108 based on the link you give, I guess this chart is made in year 2001 and month of August. 5 years ago everything is still cheap, now we are talking present where everything is expensive, the best example, petrol price. Futhermore the material cost never state clearly what metal is used, the so-called facts and figures that you give still unreal. Cannot be deny that material used is part of the cost.
You should show us some charts that show using aluminium cost how much and using pure steel cost how much. This is the best way to prove how true is your statement. With this type of unclear and misleading chart, anyone also can do.
