If it's any help, I filed Chap 7 under the new rules and was able to keep my used car. There are exemptions for personal items everything from household goods to larger assets like vehicles. There are monitary limits of course to what you can keep check the book value on your vehicle. The court will want that info. Legal aid told me that the court prefers to not get involved with liquidating "yard sale" items. It's large assets that can be liquidated (stocks, second homes, extra vehicles etc). The goal is not to put you on the street with no way to get to work to support yourself.
I do know of people who have been through Chap 7 under the old rules and kept their homes, but I have no idea what the new rules say on it.
Please do go online and get all the free info that's available to you and also call your local legal aid office for more answers.
So many of us have been right where you are. Hang in there!
