The 2006 M-45 Sport is a great sport sedan and I think it is the best value of all the good sedans out there. If you compare it to its real peer group, BMW 545/550,MB E500/550,AUDI S-6, it is as fast or faster, handles and brakes better, has more user features in the interior, and is less expensive! My car is loaded with Voice-activated Navigation ,Bluetooth , heated and cooled seats,DVD,6-disc CD changer, leather, 19 in. brushed aluminum sport wheels, etc. It is the best driver's sport sedan I have ever owned. The acceleration is very quick (0-60 in 5.2 sec.), the brakes are phenomenal, and the handling is very flat around fast corners.
Power/acceleration, Bluetooth hands- free phone use, Voice-activated Nav., Heated and Cooled seats, Understated Sporty look
IPOD CONNECTION!!! Better gas mileage with even more power, 335 hp is great but 400hp would be a world beater in the class of M-5/AMG E-55/RS-6.
