MG Windsor Colours

I am using MG Hector plus Savvy pro CVT April,2023 model but its mileage is coming down to 7 to 8 on highway due to E 20 fuel, company is also saying that yr vehicle is E 20 compliant and need not worry about engine but during my highway trip to Delhi journey, my car stopped on flyover while running and did not take start, i have to call RSA and car went to service centre by towing. In service centre they told me that while cleaning engine tank white color substance found due to this fuel injection line choked and did not take start due to E 20 petrol. Now I want to switch to EV of either MG windser or TATA punch EV or Maruti E vitara. which is suitable as safety and price wise and range and charging price. My budget is 15 lac.

I'm considering upgrading to an electric vehicle (EV) within a ₹16 lakh budget. My primary options are the Tata Nexon EV and the Mahindra XUV400 EV. While I find the Nexon EV appealing, I've encountered concerns from well-wishers regarding potential issues. Additionally, the specific trim and color I desire are currently unavailable. I'm aware that the XUV400 EV is nearing the end of its production run. Given these factors, what would be your advice?
