If it's a "lip" spoiler, buying used might be tough. Reason I say that is because my '97 had one and I put on an after market spoiler. When taking off thre lip spoiler, all the plastic clips under the spoiler that connect to the trunk snapped off, and I was trying to be careful. Plastic on this cars is getting old and brittle, this might be why yours went flying, that's if you have that style. Hate to even mention this but, check with a dealership. Your more than welcome to have my old one, comes in a sporty white with blue stripes and a quart of super glue with brush applicator.  Good luck though, hope you come across one.
