im not big into collecting, and if thets where this buggy is heading, id say hock it on ebay.
nothing is worse than having somethign that you have to spend lots of time trying to get parts for.

you have to look at it this way,(if people have parts now) ho much longer will they have them? im sure kyosho will stop making parts for them and what left will be all you will be able to get your hands on.
no way i would invest in a buggy to put it on the shelf.id buy a model for that.
