Q. Please suggest can I buy Creta new Petrol E model and modify it or go for SX model?

Well, Creta E has all the basic features which are required for a comfortable drive. However, there are some aftermarket accessories that people usually get installed to match the feature list of the SX variant. From our side, we don't suggest going for the modifications because the process will require cuts and manipulation in-car wired which might affect the other electrical parts of the car and increase the chances of losing the warranty. So, before performing any action we would suggest you to have a word with the nearest service center as they would be the better people to assist you with the wise decision.
