Got the neetmobile fixed today, putting me back almost $2900. (But nowhere near the $5500 that Albury Pedders wanted..)
Brakes, rotors, and shocks for all wheels were on the list to fix, but at the 11th hour the mechanic managed to find replacement bump stops and a gearbox mount.
Aside from the sloppy worn shifting, and part of the rear diff being worn, the minivan is back to being something to confidently drive long distances with again. Maybe not a full lap, though..
