While these are valid points, and worth looking at. I would almost bet that the motor is fine. It could be the second problem of the rust, but more likely is that where the boot opens and closes over like 15 yeras, the wires in the section between boot and car snap. I say that this is more likely, because i have heard that this is a common problem. Take off the rubber from the left hand side of the boot opening (at the top as you look at it when the boot is open) and check the wires. If it is that, you could either replace the whole lot, or just stick a new piece of wire in between the break. Hope that one of these is the problem, as they are all easy to fix...
