I love the looks of the Spartan Exec! Several years ago I went to an open house at Santa Paula airport and there was one on display. I took loads of pics as it was the first I had seen or heard of one. Absolutley gorgeous airplane! I hope for you that plans are available.

As a side note of trivia, did you know Spartan built house trailers too? I didn't, until my sister-in-law and her husband bought a property in Bishop, Calif and it included a "house" which turned out to be a Spartan manufactured trailer and the give-away was the nameplate logo on the all aluminum house trailer! So I searched out info on the internet and there is lots!
