Looking at an 07 or 08 RDX - what should I be looking for re maintenance?

Hi, my apologies if this is has been covered but I couldn't find anything using the search feature.

I'm considering an 07 or 08 RDX, both have around 100k miles. I'd like to get a sense of any big-ticket repairs, so I don't end up buying something right before major repairs are required. I'm also interested in any known "problem areas" owners have reported over the years.

I've never owned an Acura so any information is greatly appreciated.

Thanks,
ND
