Theirs a very much trending video of people buying 4 million pricier HEV over the petrol version.
So if you do the maths, Nothing beats buying an ALTO and saving money insteadd.
Something is personal choice, Trying new technology, Getting an edge over, Pampering your self while you can, In the end you earn for your self.
If you can afford a new car every 3 to 5 years PHEV is an excellent buy, With minimal depreciation too.
