well judging buy the fact you forgot you had it, you bought it on a whim and you are never home.
Id suggest putting it back on ebay, or in the forum here as a track car.
Its not a nasty auto is it, i did some welding on one of these earlier in the year, and was a nice car except for the auto box and it was a heavy chasis
As said its not worth that much really, with out the interior etc, but some one will still pay good money i guess for a track toy thats a bit different.
