I purchased the new ertiga in 2012.now I have driven 168000 km.it is a perfect family car.no problem till now.tyre milage is approximately 60,000km.fuel milage is 17km /lit on an average.service cost is little more for every 50000km.
Maruti should bring out amt version in diesel vdi ertiga.and the interior can be made more comfortable especially the fro t seats.
