Yeah it's annoying isn't it! If the extra fuel isn't a big issue then I'd look at the GS430 - I found the GS300 quite underwhelming to drive, while the 430 felt lovely plus I found the adaptive suspension on the 430 worked better than the standard one in the 300.
Plus the 430 has a better spec (includes adaptive cruise) and is such a bargain nowadays with the way fuel prices are.
I see, cheers for that, will have a look around. It says it has a 10-speaker system, I wonder if it's any different from what we have in the IS?
PS talking to you too much is hurting my wallet!
