Timing Belt or Timing Chain

I was wondering if the IS 250/350 has a Timing Belt or Timing Chain? I called 2 dealers in my state and they each had a different answer. One said it was definitely a timing belt and the other one said it has a timing chain. I'm so confused... Does anyone know for sure?

they didn't change the engines at all for 2009, so yes it's still a chain for the 2IS (250 or 350)

What's so outdated by use of timing belt? So Ferrari F360 is an outdated POS among other numerous vehicles from Audi/VW, Lexus, Toyota, Honda, Acura.... When changed on time and properly maintained there should be no major differences between timing belt and a timing chain.
