Need help on pricing 512TR

Does anyone have interest in or can help with the value of a '92 512Tr. Red/tan. 48,000miles Major service has been done not too long ago. The car has been repainted. (not because damage but the paint was worn away.) Unfortuneatly the color did not come out a rossa corsa red. It's still a beautiful paint job done 1 year ago but an off red color. The car is located in Fresno, CA. I owned the car for 3-4 years then sold it to my Brother-in-law about 5 years ago. It's definitely a well taken care of car for the miles. I'll try to post some pics in the near future. I'm (He's) probably gonna put it in the F. market letter and we're trying to establish a price?????
