You didn't mention if the car was base/clear coat, or urethane.....but assuming it is base/clear you can use something like Miguires (sp) Mirror Glaze #7 followed by Miguires (sp) Yellow #26 carnauba wax. The glaze will hide the fine scratches, and the wax will keep it looking good for a while. I use those steps on my daily driven red 95, and it looks good for 10 years old. If that doesn't do it to your satisfaction, then you could find someone that is really good with a buffer and have them lightly wet sand and buff the car again. I'm sure others will chime in with more suggestions.
