I don't know where you Live in CA but I'm in Torrance, CA. South Bay Lexus gave me a great deal that i could not refuse. I have a 07 IS350 navi with Luxury Plus package for only $39,595 plus tax and lic. My sticker says MSRP is $45,595, $6000 off sticker. The 350's with navi are hard to find, and sometimes you might have to put $500 down to be on a waiting list. Also try the Costco Discount program. Cerritos Lexus was going to give me $5000 off MSRP with the Costco Card.
