I drove my Mach a a daily driver for the past 1 year, but bought a new Focus afew weeks ago and that's my new daily driver now. Your Mustang would only suck as a daily driver if you have to commute and you get stuck in the daily traffic jams at 8, 12, and 4 o'clock, and your Mustang is a manual. Otherwise, it's cool. It would also be good if you have a garage to put her in.
