UT,
It's your car and you have to do what makes you happy. If the paint is as nice as you say now, why repaint the whole car? Most people do not realize how much work it is to paint a car "right". You will probably want the jams and trunk painted as well, right? In that case you will need all new rubbers. All windows, chrome, emblems, lights, etc.. must be removed. No matter how perfect you think your body is now, I am willing to bet once the paint is removed there will be a surprise or two. You haven't owned that car since it was brand new so you can't be sure what's under there if you didn't do the work. Matching paint is not easy but, I would give this guy a shot at a paint match and see if he can pull it off, you will spend a LOT less and your car won't be locked up for long to do the touch up. See if you can cut a deal with the guy that says if the paint doesn't match he will paint the whole car minus the fee of the touch-up.
Do you feel comfortable taking the car apart and putting it back together? If not you will have to hire someone that is capable, add this to the price of your paint job. As mentioned earlier, your lights, emblems, chrome will more than likely look a little "old" once you have a complete new paint job. I have not seen your car in person so it's hard to say.
