After driving this car for 45000 km since last 5 yrs when it was launched the first time, and spending barely 40k total in maintenance since all this5 yrs I think Datsun go plus is a very good first-time buyer car. It's affordable, it's cheap, has good experience for 5 seating, though the last seats best for children or luggage if folded.
Cars maintenance cost is very low. Say 5k to 7k per servicing depends. It's been 5 yrs and only 4 times I would have got the car serviced with 45000 km on mileage. A reliable car and the engine even on difficult terrains in its capacity.
