 I bought a new Q50 Sport AWD in mid-October.It is fun to drive. Performance and handling are great. The interior is well appointed and comfortable. It looks and feels luxurious. The major disappointment with this car is the Infiniti InTouch system. This system is used to control the navigation, climate, and audio systems. The system is takes a long time to first boot up and then is slow to respond to user input. The worst part is that it crashes and locks up all the controls. This was improved with a software upgrade but is still an issue. It's not fun when the navigation system gets reset while following route directions.
