In Canada, do not waste your money on Nav system. I live in Toronto and have had no end of troubles. Canada is an after-thought and even Lexus Canada will admit that the Nav system is woefully inaccurate and incomplete. Often advised that "house number does not exist". Entire towns in the Maritimes do not exist (St. Andrews, NB). Rely on this system and you will get lost and stay lost. In Quebec you better know the french names. System frequently sends me down blind alleys and blocked streets in Toronto. Lexus says sorry but read fine print, NICE service, eh!
I have owned 39 cars in the past 50 years including 1981 Imperial, 1977 New Yorker, 1962 Thunderbird,2002 Infiniti Q-45, 2006 Infiniti M, 2006 Lexus LS430, and this is the best yet. It outperforms the Q-45, handles better than the LS430, and is just as quiet as the LS430. The Nobel Spinael Mica is the most beautiful color I have ever owned. We drive 2500 miles to CA to visit the children and driving 600 miles a day in 4 days is a breeze. The gas mileage for a 380 HP engine is incredible. In our last trip to CA, we averaged 29 MPG. I have gotten as high as 31 MPG on a 500 mile round trip. No car is perfect, but this one is as close as I have ever owned.
Teleios wheels, reclining rear seats, automatic door/trunk closers, Mark Levinson Sound System, extension on front driver's seat, handling.
Improve the voice recognition system. My 2002 and 2006 Infinitis had a superior voice recognition system that I used all the time. The Infiniti system picks up voice commands easily and immediately. I gave up using the Lexus system because it seldom recognized what I was saying.
I owned a 2002 LS430. This car is not as comfortable and the wind noise is totally unacceptable. The dealer has installed the factory recommended fix, but my wife does not like to ride in the car because the wind noise is so bad. The LS430 was so comfortable and quiet that I made the mistake of not road testing the LS460 extensively. My assumption was that it would be improved. That was a BIG mistake. In contrast to the LS430, the LS460's seats are very uncomfortable after a couple of hours on the road. If the factory does not come up with a fix for the wind noise, this will be the last Lexus that I purchase.
Mark Levinson sound system is spectacular. I'm shocked at how good the gas mileage is. My highway mileage ranges from 28-32 mpg at 75-80 mph cruise. One tank 100% highway was over 33 mpg.
Fix the wind noise issue. Redesign the seats (figure out how they made the seats in the LS430 so comfortable and go back to that design).
Purchased a 2007 LS460L last week with 13,000 miles. Bought it online from out of town dealer. My first Lexus. Beautiful in most all aspects except for noticeable wind noise at highway speeds. For a car company with Lexus' reputation, I found this disturbing. The local dealership was very aware of the problem, replaced both front windows and "reseated" the rear view mirrors. Now I hear wind noise only when I drive at 100+ mph. Seriously. (Yes, I know I shouldn't drive that fast, but how do you otherwise pass someone who's only doing 85?) In any event, the problem was solved, I am very pleased and cannot keep the smile off my face when behind the wheel of this luxurious beauty.
Electronics and ergonomics. Controls make sense and are intuitive. The extra legroom in the back of the "L" makes people feel like they are being chauffered.
Design. Would like to see something more distinctive. The view is better from the rear than from the front, not unlike some people I know. It's not something you notice when you're behind the wheel, but my mother could have done better.
I have owned 5 Lexus. 1st was 1990. The best was last model of the 430. The new model has the following flaws, 1) Seat comfort is not the same as previous. 2) The rear view window is not large enough an one suffers from not having the same visibility as previous models. 3) The trunk is smaller due to the larger indented wheel wells that result in loss of space. 4) The design doesn't say, distinctive or luxury... instead it says, "this is a pregnant Camry."
All the electronics. Sometimes I call it my "Sony-mobile". Lots of great features. But, a little hard to program the features that are easy to use, however.
