Prices still rising. Although not a 220, I recently sold my manual TE50 T3 with 270km on it very easily, had a lot of interest/calls about it as well.
I also saw this sell at pickles Canberra, that's $15300 after fees. It was here in Canberra and my towie looked at it for me. Needed a fair amount of work and it's either had a very rough life or the kms are not correct. The interior was filth, then engine bay was gross and most panels on the outside were dinted, plus the front end, needed new headlights, bar, indicators, bonnet, fender etc.
Really good news for us owners of these cars.
