I have been lurking and learning a lot from this forum for half a year and am ready to take the plunge to buy an IS250 AWD (no RWD offering in Midwest I was told). The dealer offered me an invoice price and $750 off with Lexus financing. Is this a good deal at this time of the year around here or should I negotiate more?

Excited to own a first Lexus after saving money for several years. Wish tax here is less than 9.5%
