I will tell you that the dynamic cruise w/pre-collission is very hard to come by. Not 100% sure if you were misled, but I do know in our region Lexus does not build many vehicles with that option. I just had to special order a RX with that option and it will take 3/4 months to get. Not sure why they don't put it on there vehicles, but did a national search and only one other car within 1000 miles had it, and I'm assuming that was a special order also. If you were looking to take advantage of end of year savings, and tax benefits there is no way they could of located that vehicle in that short period of time. That particular add-on is not part of any package and is stand alone. So from the dealer stand point, and the sales person your particular LX is "Loaded", in fact that is probably the only option your LX doesn't have...which like I said, is very rare without special order.
