2009 Nissan Maxima 3.5 SV 4dr Sedan (3.5L 6cyl CVT)
I found this car to be the best blend of looks, power, handling, ride, quality and fun-to-drive compared to Lexus 350, Infiniti G-37, BMW 328i and Hyundai Genesis. It is a great value and vastly under-rated in some professional car magazines. CVT transmission, HID headlights and audio system are among the best. (Somewhat taut suspension is fine on most roads but sensitive to poor ones.) I've had it 13 months and no problems at all. Service at two dealers has been fine.
Handling, power, CVT transmission, HID headlights, Bose audio system (best of all cars tested), head-turning exterior/interior styling, Z-type steering wheel, comfort, quality. (Nissan extended the transmission warranty to 10 years.)
Gas tank cap is a bit quirky--sometimes difficult to seal.
