Need more info. What color? Do you know the build #? All original tires, belts, hoses, etc on a 15 year old car sounds to me like "Needs tires, belts, hoses, etc". How's the paint? Interior? Also, keep in mind the higher prices some of these that have been sold at are due to big-time engine modifications and not because they are all original. It's possible you might get more money for it if you part it out...lol. Folks are always on the lookout for Marauder-specific parts as they are hard to come by these days.
One thing for sure, if you want to get the most possible $$$, this is the place to try and sell it...
