I compared the RL the M35x all wheel drive autos. I found them to be very similar. Although the M35 might be slightly faster off the line I felt more comfortable in the RL driver's seat and was surprised by the sporty/firm suspension. The M35 may also win the looks category but the RL dresses up nicely with the factory flaps and spoiler. Having owned an Infinity and a Honda/Acura previously, I expect the RL to be more reliable and less costly to service. What really swayed my decision to the RL was after negotiating on both cars, the 2008 RL ended up thousands less than the M35. After a couple thousand miles, I am extremely happy with the RL.
Super all wheel drive. Keyless feature. Gas mileage.
