I purchased a new GS 430, which i had ordered. It has the navigation system (GPS) ( i was told it was DVD based before ordering). It came with the factory installed spoiler.......so there is no brake light in the rear window....instead its only on the spoiler. I imagine if u get after market spolier the brake light in it will be redundant. My lexus came with the Mark Levinson System,,,,and it is awesome.....its ASL is great which levels the sound automatically based on outside noise. It did come with a wooden steering that i love. I thought wooden steering was coming on all GS 430s. Sticker price is 54378.00<br>Thanks
