Yes, personally I would gut it completely. Remove anything that can and will burn. Carpet, wiring etc. Make sure you don't have any fuel or brake lines directly near it.
If it is gutted completely you can put on a thick layer of anti rust and some more sound proofing. May as well do that while it is empty. But it depends how far you want to go.
