They definitely drive differently than our 850's and X70's! But if you can look past the poor MPG (19-22 mpg on the highway at normal speeds), they are reliable and pleasant. I love ours for the fact that you can just hop in, drive it, park it and never worry. We've put 25K miles, I've done oil changes, tires and a set of plugs. That's it.
As for working on them, it feels very familiar and ours has not required anything odd. They are slow (but given their weight, no surprise there), the gas mileage is pathetic by today's standards but they are convenient, reliable and feel very familiar.
