I will try and find out what is the price of "new" ones. The place where I buy sells wrecked bakkie parts.
The bakkies can be anything from 2005 to 2008 models with any km on the clock.
The more km's the cheaper the item.
I tend to go for 35000km items because they are still quite new and afordable.
Example my bakkie suspention is 2005 model and 35000km on the clock. was still clean like new ones.
