Hello fellow ZHP owners. I have a question for the experts here and I hope it is not off topic. I have a relative that is interested in selling their 2004 M3 in immaculate condition with 63,000 miles. It has a full service history, Red with black napa leather interior. And something I learned here that makes it interesting is that it has a factory sun roof delete. I would like your expert opinions on what you feel is a fair value for the car. I guess maybe a market rate and the bro rate. I looked up a couple and they seemed priced very high. Do these have a rarity value like the ZHP does? Thank you for your help
