i bought an electric two wheeler, a "low power" one for a grant total of USD 835 in indian rupees last year. since then the petrol prices have gone up by 15-20%. my previous vehicle was bought in 2016 for same price. i sold it and got half my money. had to pay 400 in cash. since then minor maintenance which is basically free so for the last year i have saved almost $250-290. in 1 year. in this year i will get my 400 back in savings and after that for the next 3 years i will "earn" out of driving. note: i have grid tied 5KWH solar system at home so electricity costs are zero
