Hi guys planning to change yr2001 waja 4g18p auto to iswara 1.5 auto maybe yr 2000/2001.The reason i got this thought because of the dam expensive maintaining cost(power windows,door handle,wiper arm, underpower in city and noisy engine above 130km/h)...i drove my relatives iswara before....even thou it is older then waja but the car is seems more powerful,engine also more refine and the power window,door handle all that are all still working which lead to less maintenance $$??to add the tires are also cheaper as the size are 13 inch only rite??should i stick to the waja or change to iswara??
