The work I have done my self, maintenance and repair, have been straight forward with the help of the factory service manual. Obviously I do not have the active suspension option. The down side of having a car that did not sell well is that parts are not easy to come by outside of the dealer network, and the ones that are will be expensive compared to similar cars produced in greater numbers. Love my car and do not understand why it suffers from accellerated depreciation. It may be second best to a Lexus, but, like getting to the world series and losing, is not a bad thing.
Car is a pleasure to drive.
Has reasonable rear seat space. Passengers enjoy being driven around in the Q45. Get compliments on the looks. Great for long distance travel. Surprising nimble in the snow.
