I bought my SS Prem two weeks ago for $1500 over dealer invoice in WA. I had called around to dealers in CA and most were at MSRP. One
[email protected] sales manager in Petaluma told me I'd never find a 2012 for less than $10K over MSRP, that everyone on forums lies about what they paid, and that I'll always be competing with wealthy Middle Easterners and Asians who pay top dollar to have them shipped overseas. He wanted $25K over MSRP for a white BE and said he'd consider $15K over if I had an interesting trade. I just laughed at him and told him he was delusional.
A week later I had my car under MSRP, no hassles, no haggling. I called the dealer, he gave me the price, I said that was fair. Done deal.
Hold out for the right price.
