Nice looking wagon, one of the rare '85s with D24T and manual in a wagon body -- a one year only combo.
Sorry to see you leave the IDI fold but hope it found a good home. And hope you invited the new owner to join us here for any info or resources they might need to continue keeping it on the road!
Curious your reasons for forsaking the IDI engines at this point, considering you clearly are highly knowledgeable of them? Summertime travel in the mountains too much effort to stay cool? Are you transitioning to TDI cars or something else?
