After researching several cars in this class including the BMW550 and the Lexus IS350 and others, I selected the M45Sport for its handling and value. Two problems for a 65 year old like me are: 1) Stiff ride for long trips. 2) Road noise. Gas mileage is another problem. Toyota has the technology backwards: If you want the sensing of front traffic while on cruise control or lane change notice, then push a button not the other way around. Excellent car overall.
Reliability. Adequate power. Very good handling. Very good sound system. Value for the dollar.
Insulate the car for a more silent ride on the road. Integrate a soft and a sport ride for the choosing. Reverse the choice for lane changing sensing and front car sensing on cruise control.
