I plan to possibly get a 07 IS leaning towards ML/Nav + Sport, however I notice something odd. I see some of the items in these packages are shared b/t packages. For instance the Premium and Sport package both have heated/vent seats, perforated leather. Also 18" are put on the car already on southern allocations but are in the sport package as well. Common sense tells me I shouldnt be paying full price for some of the packages otherwise I would be paying twice for one thing.

I would think it would be fair and right for the dealer to discount the packages accordingly because of shared components but would they actually do this?

You cannot get the packages in conjunction with another Package.

IE, you can get Premium, lux or sports packages.

The Sports package includes 18s, so you dont have to pay extra for them.

I wish i've waited for sport package. Premium package is such a rip off. I had to pay 1200 for PP and 800 for 18" wheel. If i've waiting for sport package, it's only 1800$ more but you get so much more.

no wonder they took off the sport package for Build your IS for my zipcode, looks like sport for my area is a special order only

When I bought my IS350, I was a bit confused. The packages on the dealer website did not match the packages on the Lexus website. I asked the salesman and he said that different areas are getting different packages.
I wanted a plain Jane IS350, but they all come with 18" wheels in Houston. I like the wheels so it's no big deal, I don't think they are charging you twice for the wheels. Even though mine is a base model for my area, the charge for the wheels is on the sticker.

did the premium package come with it, all southern states supposedly come with it (i dont like wood personally) looks like i have to special order sport ML Nav yay....

I don't think you necessarily have to special order Sport ML Nav. They do make the cars in that combo. When I got mine, I was surprised I didn't have to wait for the car. The cool thing was the car with the combo and the color I wanted was already at Long Beach Port when I did my negotiation.

Just buy out of state and get what you want.........Truck the dog gone thing to you...
