That included maintenance. Still a lot of money. I would expect a W140 to require similar (or even more expensive) upkeep as the years roll on. Have you considered an E39 5-series? They have much of the same good attributes of the 7, but in a smaller size. The 528i especially should be more reliable than a 540 or 7-series because of its more simple design. I found these cars to almost rival their bigger brother 7-series in quality of materials and fit and finish, while being more fun to drive.
