If you can afford the extra cost of added insurance, gas, maintenance.. etc.. I wouldn't be so quick to dump the Focus.. The more u use ur Z the more maintenance yr going to need.. (r u ready for new tires yet
they go quick if you use as a DD..
I use a Ford Explorer for my chores (Shopping & dragging family around) Camery as a DD & my Z when I need to be alone on the open road...
& maintenance on all 3 is fairly low because I don't beat any one car too much..
