Just off the top of my head: Spica repair. The Montreal has a unique 8 cylinder Spica pump. Here's another: Refurbishing the interior. Serious body work. My understanding is that the engine itself is pretty straightforward, although it is not precisely two Nords joined at the hip either. I don't know about the tranny - might be pretty hard to find (read "expensive") parts. It's not as bad as a Ferrari, but it is def. up a category or two from a regular Alfa.What would constitute a 'major' repair? Engine rebuild? Transmission?
Are there mechanics around that would be able to tell what was wrong with the car given how few of them there are?
