I've been a long time BMW owner for everyday driving..currently and X5 4.4 and 540i, and like many, have not been happy with the changes BMW has been making in the last few years. Aside from the X5, when the time comes I am unlikely to replace the 540i with its successor. I've been keeping my eyes open for other marquees to fill its shoes down the line. I've seen several Maseratis (Cambrio's) in the past year that people seem to be using as daily drivers and would appreciate some input from anyone here with experience in this area. I would especially be interested in hearing about the Quattroporte. What's the reliability factor? Service requirements? Driving comfort and experience? Frankly, I'm just not familiar with the line. Thanks!
