Well it isent that popular of a car to customize, but I think lower it, put on chrome wheels, wide whites and some pinstriping.
If it's anywhere near as nice as the picture makes it look, I'd just drive and enjoy it. Looks like a beautiful ride to me!
I'm working on one right now, the best part is that are almost a dime a dozen. So you can customize one and not have to worry about really ruining anything. They do look good lowered about 2 inches in the front.
