Lexus have a 5K service interval and I don't see them changing anytime soon. They've got a great reputation for reliability and they want to keep it. However, they have another problem....recommending low viscosity oil to help Toyota with their CAFE averages.

I think that it IS an environmental issue that has driven/forced the German car makers into extended oil change intervals. I remember the first time I saw the new C-Class with chunks of vinyl cut out of the pan that holds the spare tire down. This was the first of many indications that the Germans were into recycling. You also have the wiring harness issue, BMW's with recycled rubber dashes and many other indications.

Trying to find an absolute bullet proof car now is difficult. I want a car that drives like a BMW, is the size and style of an E-Class and has the reliability of an LS-430. If I didn't have an adversity to paying interest, I'd stop paying cash for my new cars and start leasing.
