Well, just hanging around these forums in anticipation of a new Mustang GT makes a man think. I've seen a lot of cool ways to modify these cars (there aren't very many for a 97 Thunderbird). Here are the things I want to do relatively soon after I take delivery (finances permitting).

Hood struts
Taillight bezels
Painted mirrors or mirror covers
3M invisible front end shield (or equivalent)
CAI and tuner (leaning toward the Tunable Induction/XCalibrator combo from Modular Depot)
FRPP Axle-backs (I love that evil sound!)
Window tint
Rubber floor mats for winter

Down the road, I would also like to add:
FRPP Handling Pack
Aftermarket shifter
HID's
Silver stripes and possibly a ducktail spoiler

A question - how in the heck do you pass the days waiting for your baby to be born (delivered)? Just wondering...
