Its really strange to know that although Innova is a great vehicle to ride, its maintanance cost is very high. After 10, 000 KMs servicing costs more than Rs. 6000/- just to get the standard service done as per the vehicle booklet. Therefore, after 10, 000 KMs the service costs more than Re 1/- per KM. After 3 years warranty this cost rises from Re 1/- per KM to Rs.4-5 per KM. This sucks big time.
Because big companies are known for low maintenance cost for diesel vehicles. Like Mitsubishi lancer & Opel Astra diesel are very low maintanance cars. Think before you buy. NEVER buy a pre-owned or 2nd hand innova.
Good luck.
