The "brain trust" on this forum is just so amazing to me with so many smart, humorous (I know--"humor this!") folks sincerely giving their best advice. Without this site I might have been just another seller of a Speedster with more issues than I could cope with rather than a very satisfied and thrilled owner with pretty much an issue - free car and some abilities I didn't have before meeting new friends on this site.
So many of the posts on this thread would produce great results---almost any one picked at randon would help---they are that well thought out. After seeing so many great options presented above I myself would proceed like this:
1. NOT send the car back to CA again! You already know this is a black hole. Save the $800 too.
2. Take J. Steele up on his offer to supply the parts---that's the very least he could do. Step #1 would be to list 'em and get the parts list to John S. asap. Request that John tell you what he knows for fact that would fix leaks or about anything else he knows since starting production on these coupes. Do a gracious post publicly thanking John for the parts and knowledge and throw him a bone to offset the stress we have all put on him by having Theron remove all posts relating to this whole affair---offer this up front to John. Leave the door open to go back to John if additional materials or parts are required.
3. Have our top-knotch talent pool who have already signed up for this project to move forward as Gordon suggested earlier in a smart team-based step-by step fashion.
4. Enjoy your sorted out car knowing it is a tribute to the class folks on this site and a freely given gift from your Speedster buddies to a fellow member.
Last note---I would be disappointed ,on a couple of levels, to see you sell the car right after getting it straightened out. I want to see you and the car at Carlisle next year!
Whatever you decide---get with it so you can enjoy the car before winter! Good luck, Tom----Jack
