Looking at the options, it would be $25k++ ish to put in a new autopilot.

The airplane is soooooo stable I hardly use it at all, but...

I took out the servos (wing panels), the brain (over rear most seats), and control head (by knee), wire tied their airframe connectors so they couldn't hang anything up, and sent to autopilots central to bench debug the whole thing.

About $5k. Works like new.

Pretty much the only thing I ever use it for is straight and level, with bearing and altitude hold. Mostly just to play with it.

Simply tweak heading knob until the projected 50mi track vector on my GPS overlies the next place I want to be, and presto.
