Welcome to the club!  Nice choice with the 75 too!  I've had mine for about a year now and it's been really reliable,  Dad helped me build 2 cars into 1 because the first one had some rust we didn't know about.  The motor is still unopened, we just put new seals in it.  As far as the electrics go, I think the 'stories' are way over reported.  Most 75's are getting on for 20 years old though so they're not without fault.  The motors need care, expecially the V6 with it's timing belt.  I do my own work (sometimes with a little help ) and as a first year apprentice I find it very affordable.  I saw in another post you were looking for some pictures of the engine bay and the interior.  Here's some pictures of mine.  The interior shows the original tweed material on the door cards and the original seats retrimmed in different material by the previous owner.  The tweed material came in the earlier cars on the seats as well but usually disintegrates.

Cheers, Scott

Surely we aren't all V6 owners, there must be someone out there who can advise on the joys of the Twin Spark
This is an important thing to ponder, do I want that noise that can only come from an Alfa V6 along with the higher maintenance costs and the tendency to understeer due to the greater wieght over the nose or do I want one of the most advanced engines of it's time with power & torque spread over a huge rev range not to forget fuel economy only dreamt of by owners of older N/A Alfa 4s. Did I mention the body kit that comes standard with the TS but only on the 3.0l V6. More Things to ponder.....sorry
