I have had all the luxury sedans. You name it and I have had it including BMW, MB, Jag and Infiniti. I leased the RL with a few doubts but it is a driver's machine. The 4 wheel drive is really amazing and you can push this car hard on the curves and it comes back for more. Fit and finish is superb. I look forward to the office commute every day.
The high tech features are amazing and easy to use. The GPS is excellent and the stereo is well amazing. Fit and finish is superb.
None... this thing feels like a v8 but is fuel efficient
