One of the favorite places for a scratch or chip is on top of the roll bar(s). It's such a handy place from which to push the car!
If you want to maximize your power, have your carb tuned/jetted by an expert. Rob at Keith Craft got 49 rwhp out of my 392 from just this.
Coolant leaks and tranny leaks around the speedo cable have also been common.
Check the parking brake adjustment and the throttle cable linkage. The parking brake can sometimes be too loose. The throttle cables also have a history of being loose. You push the pedal and depress 1 1/2" before it moves the carb linkage.
The fit and finish are usually top notch-check the spacing between body and doors, you'll see.
The paint is usually quite good, although I've seen some with slight runs or orange peel.
After a couple of months or 500 miles or so, do a once-over underneath the car and check every bolt/nut you can find for tightness. It's surprising the things that work themselves loose.
Mark, I truly hope your wife remains interested in going for a drive. Mine was so stoked until that first stiff ride and pop of the throttle. She still thinks it's the most beautiful car on the planet, as long as she doesn't have to ride in it!
Enjoy and take lots of pics! This is a magical time and you'll look back on this like a birth.
