One of the difficulties faced by Rare Spares is how many and what parts to make first. There are literally hundreds of parts in the pipeline that people want. There is a manufacturer that produces the majority of rubber parts and is capable of making the tooling for ongoing productions. However there is also the reality that there is a cost to produce any item and that it must recover it with sufficient sales and profit. The sales potential for the rubbers are low and therefore it is lower down in the list for items to be made. All Rare Spares outlets have a "WISH LIST" for items to be added to and this is sent to Head Office monthly. This is then put on the computer so they can then evaluate what is popular and has reasonable requirements to warrant going ahead.
