Used car dealers can download the latest edition of the Retail Motor Industry Federation’s used car guide here for free.

The guide covers advertising promotion regulations, good practise and consumer credit regulations.

Alistair Manson, head of the RMI’s national franchised dealers association, said: “In light of businesses’ increasing responsibility in these areas, it is critical that members are aware of what they can and cannot do when they promote their businesses. This is essential reading for all RMIF members."

Chapters will be released periodically throughout 2006, and the next installment will cover insurance and warranty.
