Better car and more car than a Focus, bigger wheels, more power, better interior, better styling (although I love my roof mounted tail lights), better price. Fully loaded with the 2.3L, leather, moonroof, 17 inch wheels, etc... a 3 will run me about $2K less than I paid for my ZX5 with no moonroof. I did opt for advancetrac though, which tagged almost $2K onto my sticker. Seeing what Ford is doing to the restyled Focus (Hey, lets see what the car looks like if you take away all of it's character!), I'm looking even harder at the 3.
I wish I'd waited 2 years and kept Mean Green, screwed up secondaries and all... My ZX5 has given me 2 years absolutely problem free and I do like it, but the 3 is better.
