Maybe this is normal for Texas, but you can do much better in Southern California.
Last Thursday (Last day of the month), the lowest quote I got for MSRP $42,052 (NAV, Premium Plus, and Accessories) was for $37,400. This was in Ontario, CA. I didn't take this one.
The lowest quote I got for MSRP $45,732 (Luxury Plus, NAV, Mark Levinson, XM, Spoiler, and Accessories) was for $41,174. This was in Newport Beach, CA. I didn't take this one either.
I used these as leverage and I went with one with the Luxury Plus, NAV, Mark Levinson, Accessories and Dual Exhaust. I didn't want a rear spoiler. MSRP $46,391. I got it for $41,500.
The internet quote system was a great tool.
