2006 impala

I just recently bought a2006 impala with 24000mi. just wondering if anyone has had any problems i need to look out for before my warranty runs out.
also how does the impala stand up to the nissan altima and the chrysler 300, they were my first and second choices, i had to settle for my third choice.

You may want to put this in the impala section. They have a better understanding of impalas. Here we generally only talk about nissan maxima. However I think you should have gone with the altima 3.5 choice. =)
