when to replace belts on G35 sedan

[andy2]

I came across a posting in another Infiniti G35 forum in which a user said that the dealer recommend replacing a whole list of belts after only 30K of driving.

My question is does this make sense? I thought the only belt you need to replace (at least within 100K) is the timing belt which then only at around 80K or so. I just hope my G35 sedan (just bout a week ago) won't be too picky when it comes to maintenance.

My last car was Honda Accord and the only belt I need to replace was the timing belt.
