Ask him/her for the "vehicle inquiry report" which lists your VIN, color, trim and Options. Make sure it all matches to what you are expecting. Get this on paper so you can take time to review and confirm it, then hold it to ensure they don't change it. Luckily this last time, I had mine in an emailed PDF because they tried to tell me I hadn't ordered it. I would also confirm it with a current dated VIR again when signing the contract and or prior to delivery.
