Ya know, i just heard of a guy who basically F'##d around last year with their credit to the tune of over a couple of hundred grand and this year they spent around $1500 to just declare bankruptcy. I asked the lawyer if this was legal and he said 'apparently there are a lot of people right now declaring bankruptcy and doing what they are doing' The excuse is bad economy, no job, bla bla bla and get this, they are not liable and after a couple of years it's not even on the credit history. Seems it's a going trend and legal as long as you dont have anything significant in your name.
By the way just keep the Z and park it in a corner. Do you realize how hard it is to find a nice donor car right now? I'm looking for one for a friend of mine and they are either too much, rusted, gutted out etc...
So just keep it for now and wait, things always have a way of turning around, and judging by the amount of work you indicated on your website, id keep it.
