California DMV dealer complaint: what evidence should I include?

California DMV’s complaint materials say to include copies of supporting documents such as contracts, warranties, receipts, cancelled checks, repair orders, photographs and letters. Do not send original documents. A clear timeline plus the dealer’s name, transaction details and copies of what you relied on can make the complaint easier to assess.
