if you have spare funds why not 30% is not bad. Highest are usually 50% and those usually only during holiday sales. Predicting which car will get ES is not easy unless you have some intelligence like game files to go buy (E.g. Ford GT 2017 which was predicted recently)

I am in no position to speculatively upgrade cars for ES yet but it all depends on how much funds you have if you can spend while remaining gold positive surely go for it
