There's a few of us on here that have moved from the EP3 and to be honest there is not much difference, the insurance is about the same as is the servicing the only difference is the fuel costs, it costs about £20-£25 more to fill the Z up but you will get an extra 100 miles more than in the EP3. I drive 50 miles a day to work and back and have been averaging 20.8mpg but some of that journey is on a dual carridge way.
