Restore it!!! My chassis was ruthlessly removed with an angle grinder by the PO. Take plenty of pictures of it in its undisturbed state if you would! He cut the car up to a point where the front end now sags. now I have to make a bucks to prop it up and glass it back in.
Serge has a good section on his blog about how he got his out. Some say the bottom is easier, some say cutting through the firewall is the way to go. Mine was cut from the bottom and it damaged the body.
