 Fast, Fast & comfortable-no problems did not get nav system-too hard for me.Clock hard to read--Drives well at speed near & over 100. Tested one at my nearest dealer, but he could not locate a millenium jade.  Bought from a dealer who could get my color.  I must be careful to check tach to see if engine is running-so quiet & vibration free.  Wife loves to drive it also.  Original tires have 1/3+ tread after 49K miles.
