Really cool!

BTW just out of curiosity, any other metrics you can share about how accurate it ends up being? Like RMSE/MAE?

And I would guess that there's a significant problem with outliers. Accidents for new cars, replacing an engine+gear for old cars, etc. Is this the case?

Yeah sure so the MAE is currently ~1.4 years, and the RMSE is ~ 1.8. Yeah there is trouble with outliers, and unfortunately in the data I have there seems to be no way to tell when an outlier has occurred. For example, if a car has an unusually short life I can't necessarily tell if that is from an accident or it was just poorly built/ maintained. To try to counter this I have trained only on cars where there is data for more than 1000 of that make/ model in the hope these outliers will get averaged out.
