90% Complete, 90% left to do.  Prior builders choose good upgrades/changes  over the years, such as dual hydraulic brakes  Good to excellent detail work.  As the latest builder (goal is to complete in 2 years), many things need to be checked out, validated during the start of the process.  Engine was assembled in 2010 and never run.  I've got the turbo upgrade kit to put on and will do a partial teardown/overhaul at the same time.  The first 1.5 years of my ownership is gettting the garage ready for this unexpected purchase.  Some riveting left to do, partial glass panel to complete/test.  Decide how to implement ADS-B out, and in if feasible without fully investing in new glass.
