Pozy

I have been looking for awhile, to replace my 2005 Ford Explorer, which I pay $500 a month on. I got an add from one of the salesman that I deal with at my local Lexus dealership on the 2009 RX350 model for $399.00 for 36 months lease. I was wondering if that is a good a deal or wait until the new models come out. I was also wondering what other people’s opinions on the RX350 are. Thanks
