Tyres and servicing aren't any more than the 911, which isn't any more than the 350Z was, but the fuel thing is definitely a huge jump from the current 30mpg I get from the Porker. I could live with 19mpg though, as I only got 23mpg out of the Zed so no hassle dropping back down. It's more the range that causes issues, as I like getting 400+miles out of a tank on a run atm. Still, the Zed isn't much better, so that's not a huge issue I guess.
