Have had the Sentra for 3 years now. Take the CVT out of overdrive when you're going 20 MPH and punch it, and the next thing you know you're going 80. I can't imagine what an Altima 3.5 with CVT is like. I think I have had one squeak in the dashboard. Also, I still haven't figured out how to fold the back seats "down." It's complex, trust me. But, it's an all-around great car overall.
