dear i have installed eps of japanese alto .newone is as far as i believe is not available or if it is available it will not be that much reliable as the eps of japanese alto.The cost of eps is Rs4500 and Rs1000 is the labour charges. Cost of power windows is Rs7000 and installation Rs1500 respectively .The power mirrors were short in the market .I will be get them in a month or two .The power mirrors cost Rs4000 approx.and Rs 500 approx labour charges.I will also install rear defogger screen which will cost approx Rs3000 in exchange with the old screen.In case of power windows,the old panels will be exchanged with the power ones.
Note : These all changes will void your warranty because according to paksuzuki you have done electrical alterations in car.But as i completed 37k km so i didnt worry about warranty.But i think you will be aware of the fact how much paksuzuki is good in claiming warranty so the warranty is useless.
