 Traded in 05 Maxima SE for this car. Am not disappointed in the least little bit. They say it's suspension is load, but the Maxima had the noise in the front instead of the year. If you drive the speed limit in Sonota it'll get 34 mpg at 4200 miles on the odometer. The Maxima SE might get 29/30 but on premium fuel, and when do you need 290 hourses driving around Springtown. Sonata is smoother than the Maxima but has more road noise, but not unbearable to any extent. XM is wonderful, infinity sould is on par with luxury brands. Well made car free of rattles, and never back but for oil changes, believe at this point I may as well not look further than Hyundai for my second car when ready.
