You should'nt , you should get what you want for it , hence the reserve , BUT , make sure to put the reserve in the top line and the bottem line ( and probably the middle for all the people that just read a few lines of the ad , LOL !!) so people don't have to guess at what it is .
One thing for sure is you will never please everybody so just worry about taking care of your family , if someone wants to save that car bad enough he will step up and pay ....
