I would have to agree with the posters here. SRT6 if you can find one within your budget. Power and handling beyond a mustang.

Downside... only 2 seats.

Upsides... read the features thread here.

As to daily driving I'll say this: I've been daily driving mine since I bought it last year. Love it... even on crappy California roads. Even took a 2,000 mile (each way) trip to see my folks back east. Never got back cramps, just leg cramps after sitting for 3 hours straight. Learn to take a 10 minute break every 2 hours and you'll be just fine on a long road trip in these cars.
