I'd do it. No matter what, its still a mustang. You will see 50 on the way to work, and while yours is a little different, it still looks like the others. How many ISFs do you see rolling around?
The chief of anesthesia at my hospital has an ISF. I've ridden in it, its an awesome car and very comfortable. I have an IS-250 (wife's) and its nice to drive, comfortable, and leaps and bounds above her friend's Escalade as far as luxury.
