Kind of hard to answer your question. The reason I say this is, I have no idea how this Rover was maintained, does it have any current issues. What has been done in the way of current maintenance and Upgrades if any. My 1997 served as my daily driver for years, but now it is my off road vehicle and winter driving vehicle.
You same question could be made toward any vehicle on the market... with the same results. If it has been taken good care of and maintained as it should be then it could make a good daily driver, not cheap on fuel but it will get you to and from work.
On the other hand if it has been neglected or if you do not keep up on it... it can be costly if you take it to a dealer or mechanic (same can be said for any vehicle).
