closed usedmotorcycle.us what's it worth?

[2ndWave]

I have a party that wants an asking price for usedmotorcycle.us. At a moniker/traffic auction in march 07 usedmotorcycles.com sold for $105,890 USD. Checking Adwords it seems the singular and plural have the same amount of search volume. Has anyone looked at the sales of words which are the same(including singular and plural) except for the extension and come up with any formula for comparisons? Such as a .us is 1/20 the value of a .com, a .net is 1/10 of a .com etc?

Thanks Dennis
