altima rocks.. when compared to accord and camry.. i used all three.. when honda feels light, camry feels like a skate board where the nissan scores as an athlete!!!!! smooth, reliable, high revving, high torque engine in it's class!!!!! and ofcourse it has better air conditioning and comfort than other two... (personal opinion)

when it comes to the maintenance,nissan is more durable than other two. nissan's service is prompt. as i have seen.

in my opinion, go for altima if you want cool executive car... best of luck:)

check this tread. it's all abt toyoyta...
