Added (1). Which is faster automatic trans only?

Maxima

I think that the maxima has more luxury in it than the honda civic, but the Civic has much nicer driveline and greater reliability, the maxima i find has too many mechanical issues

The Maxima for smoothness and luxury.

The Civic will have better handling and be more "sporty", but that wasn't the question you asked.

You are comparing apples to oranges. Of course the Maxima is has more luxury and is faster. It also costs around $15,000 more.
