I was at the auction. I knew the roof didn't go down and was pretty sure I knew why, hence why I bought it, thats how you get an edge. Other than this the car was an excellent example with no other faults apparent and no swimming pool.
I agree, my mistake was allowing it to stay at the auction for ten days. This is simply a forum thread. On a forum we moan about things, let of steam...its the cyber version of being in the pub.
Whether or not I make a profit will not change my life. Its taken 2 weeks and a lot of effort to dry it out. Seats out carpets out etc. The rear control ECU turned out to be fucked, but I got a used one for £130 and contrary to all the information, it turned out to be plug and play. I sourced the roof components including the chewed up drip trays for a very reasonable £320 from a Porsche main dealer. I now have the challenge of putting it back together which I am going to have a bash at. The only electrical issue which remains is the PCM which I am pretty sure is related to the battery being disconnected and hopefully something I can figure out.
I'm cheesed off at being put in this position, but in a way its been strangely satisfying to overcome all the hurdles and get towards the point where I have one of the best examples of the model for its year on sale.
