To each his own
I like the new 5.0 Stang and it's an incredible bargain for the amount of power you get. However, I still prefer my Z for looks, handling, and power it does put out.
Plus you don't see too many Z's as compared to the Stang. Which is the same reason I also ride a Harley Night Rod Special and will soon acquire a MV Brutale 1090R
Congrats on the new ride and I hope that voodoo from your Z doesn't rub off on mine!
