Latio parts seems lasting up to now, although mine is low mileage, feel the car is reliable and economical still.
Mine is 5 years old, so far if due to defect is only change steering coupling once. Other stuffs due wear and tear are tyres, battery, air con filters, all changed thrice. Air filter, CVT fluid, beltings, wipers, all changed once.
Hope that by regular servicing and normal parts replacement, the car can last another 5 years. Other than that, think nothing much i could do if car got design flaws or inherent problems.
