2010 Nissan Altima 2.5 S 4dr Sedan (2.5L 4cyl CVT)
Quick enough with the 2.5L 4cyl that I chose it over the V6. While the CVT takes some acclimation, I am now completely comfy with it; careful throttle application lets you accelerate to 45-50mph within traffic, never exceeding 1500 rpm. Excellent mileage. The gadgetry all works as advertised: bluetooth connection, very useful voice controls, etc., as well as the "magic key". Brakes are strong enough, but I haven't tested them all the way to fade. I do wish for slightly larger diameter wheels (would smooth the ride some more), and a bit more confidence stuffing the nose into a high-speed turn, but the overall handling/ride/comfort still beats the 2010 model contenders in the 4 cyl sedan class.
Electronics work well. Bose system sounds good. Good legroom. Nothing "loose". Very quiet at 80+ mph, owing much to very tall top ratio and good aero design.
WHY does this car have a 160 mph speedo? It won't go that fast if you dropped it. Scale makes it challenging to keep in legal band. I like CVT, but it takes some patience and experimentation to get used to it.
