Rizzo method isn't a bad way to go. I've done it in the past long before I can remember someone calling it Rizzo.shifty said:
This time, I just found a good price that was ~$1500 over invoice from an online leasing company and presented it to the sales rep. He had a choice. Match the price or I walk. After many tries by him and his GSM to convince me otherwise, I walked out of the dealership. Just as I was closing the door to my car the sales rep came running to me and matched the price.
If I had the opportunity I would have gone the Rizzo method. At the moment, I just didn't have the time.
