Hey yall!

Been doing a lot of relearning of SR4/5 and was curious to know if a methodology existed for transferring vehicle stats from 3e to 4e and/or 4e to 5e.

I know that all three editions specifically have pulled various vehicles from past editions but I've never been able to find the equations or methods that were used. This struck me as a nuisance given the published character conversion methods.

If there isnt, is there a broadly accept homebrew method?
