Welcome to the forum!
(I do not know about Sacramento.) I bought all three of my Infiniti's from Frontier Infiniti in San Jose - three different salesmen. All three were excellent-to-outstanding deals (but I did have to "discuss" the deals a lot) - my 1991Q was 33k (MSRP was 39k), my 2003M for 34.5k (MSRP was 43k).
I don't think there is any such thing as a haggle-free car purchase!

Unless AZhitman (Greg) was still working at Scottsdale Infiniti ... then he could ship you the car you wanted at the right price.
Their service people are good. William Perry in particular has been there for a number of years and always does right by me.
