You would probably get more by parting it out, but even still I don't know if you can make all that 9k back by even doing that. I would post up the seats and the wheels on sr20forum.com. Alot of people take those parts and swap them on older sentras/200sx's

If you do part how much would you want for the wheels?

Oh and the 6speed trans is worth quite a bit to so I would post that on there too.
