Car Park Project - Update 2

My project for the car park is going well. I built the frame out of two metal drying racks and wood, The racks form many squares which allow many places to hang the objects from, the two pipes will go across where the top of the two walls currently are and will then be attached by cable ties. I decided to use baubles to build up the body of the work as they are easy to hang and also reflect light well. I have decided to create a cube shape out of the hanging objects as to resemble a car after it has been crushed.

It is proving difficult and expensive to obtain spare car parts which aren't too heavy, I have bought two rear view car mirrors which cost £5 each which are light me weight, however I cannot afford to by any more. Ive been to four scrap yards who all said they crush the cars without removing the parts I need.
