I truly love this car. I originally bought it for my father so I could give it to him in March (his birthday) but I now use it every day myself. I have contemplated buying another aurora for him since I sent my father photos of the one I bought for him and he keeps telling me how much he likes it.
This car has gadgets that my mercedes benz does not have. The interior is luxurious and extremely confortable. I love controlling the radio and cruise control from the steering wheel, and the overall look and style of the car. This car looks sleek from the front, side and back.
For those that complain about the gas, let's get real. You are buying an 8 cyl engine. You can't expect 30 miles a gallon (I get 15-18 in the city).
See http://aurorah.proboards47.com/ the Aurora Club of North America, the biggest Aurora forum on the net, for information & discussion about the Aurora.
