You can give it a shot
https://celicahobby.com/forums/ubbthreads.php/forums/40/1/for-sale.htmlThough, what someone will pay depends on what condition its in, if its painted, has been repaired, is sagging, if it was customized, if it needs to be shipped or can be locally picked up, where you live, and how quickly you want it sold vs the community demand for this product.
But still, take a few good photos and post here and on any of the other Celica websites you come across. Also, if the reddit / facebook communities allow it, post on those also. Its normally better to sell to someone locally, than having to ship these types of products.
