When I placed my "order" (color, packages, etc) over the phone, the dealer faxed me a one page document (i don't have it here at work) that looked just like other documents I have received when I purchased cars in the past. It had the dealer's name at the top of the page. It had my name, address, type of car, model, year, color, a space for a VIN number, it listed my car and options with prices and then it had the tax, title and license amounts listed and a final purchase price (note: next to the base price it said "M.S.R.P."). At the dealer's request, i initialed it and faxed it back. No additional money required. I was told my deposit remained refundable. I don't know if this is what you all (or y'all here in Texas) are calling a purchase order, but I am a lawyer and it satisfied me.
