Went for a test drive yesterday. So called "World's largest Lexus dealer" had only two 450h. One 2-wheel drive in the showroom and one 4-wheel drive not even for test drive (according to the sales). My wife and I took turns driving for about 5 miles each trip, and we were NOT impressed at all. With all the new technologies Lexus put into the new model, we did expect more power, more torque, but, we just did not feel that. Compared the new designs inside and out with our '08 400h, we just love ours much better. Yes, it's more fuel efficient, NAV now has HDD instead of DVD, and they are able to keep the price about the same (by offering steel rim on spare tire now goes under the trunk?), it still does not convince us to trade our '08 in. Besides, there's only limited quantiy / colors are available (the salesperson showed me there will be only 6 available this month with only 1 4-wheel drive), and there's only one option you can choose now (go check it out on Lexus website since dealer doesn't even have printed brochures). We are really kind of disappointed about the new 450h if compared to '08 400h.
