So took it into a restoration shop. For 3k they can go over the whole thing, install the cat and air pump, make sure it's all mechanically sound, etc. Basically help get it to pass emissions and be free of any hidden gremlins.
Full restoration to show room quality: $45k. Ouch.
Trying to decide what to do. I think I'll start by installing the cat and air pump myself and just seeing if I can get last emissions. After that, going to reassess where the Scrambler fits in our lives and if it's the right car for us or not.
