Main dealer is not necessarily a must. Most on here will tell you that a good specialist is much better than main dealer for servicing. Somebody like horsham Dev, japex, clarks etc...
As for used as a daily ....it's a great daily. Comfortable, quick, refined and a joy to drive. It's not overly fuel hungry and a 10 mile journey won't hurt it at all. Hop on board buddy you won't regret it.
