WITHOUT Sport package the ride is terrific, car rides quietly. Sport pkg is too stiff, sport seats wrap around too much making entry/exit more difficult
At this moment the computer shows 27.6 mpg for combo city/freeway/around town driving. True, it uses premium but that is excellent for a car this size and performance.[mpg is without using A/C]
Engine is smooooth! Lots of low speed torque, quiet. About as smooth as the car it replaced, a Lexus LS400 V8.
5 Series is smaller than my 1993 Lexus LS400 but the handling is a little better, ride is very good, although the Lexus compares favorably. I wanted a change so I went with the 5 series, the 7 series is a dog in my opinion. The 5 series is a better blend
