Your story sounds very familiar! My GT6 sat in the garage for 15 years, I did bits and pieces but then, an injection of funds, followed by my daughter announcing she was getting married "And by the way, I want the GT6 as a wedding car". 7 months of solid effort but I made it!
I found the old forum and the people on it invaluable during the rebuild. The new forum is getting there, it has the same people, why wouldn't it?
