We purchased used grand i10 in 2019 as I always am a big fan of Hyundai cars. It was really a great experience for me. Diesel engine of this car is very refined as cabin insulation is very good, so it gives riding comfort without any outside noise when windows are closed. I drove it through highway, hilly areas and also bumpy roads and it has amazing performance. It is a perfect hatchback with looks and modern elements like DRLs, sharp design cuts, very smooth suspension setup. As a diesel car it gives me fuel economy nearly of 22-23 km/l with AC on. The maintenance cost is very less. You should change oil after several kilometers and do wheel alignment also for which the cost would come around 5000-6000 Rs. It depends upon your use but it is one of the best family car. If we talk about interior design, it's fabulous with all facilities and top quality material used all over. It has a dedicated AC unit for rear passengers, enough storage area on every door and boot space is also good..
