If someone wants to buy a new car in 4 lakh then I would say just go for renualt kwid. It is much spacious then maruti alto and tata nano. Three adult can be easily sit in back row seat. Dirver leg room is good in space and even 6.2 feet tall man can easily drive the car without any discomfort. Its engine is 798 cc which is good in performance. Kwid gives a mileage of 21( approx) in cities traffic and 25( approx) on highways. It is a comfortable car and since I am using it for more then 3 months and did not find any discomfort while driving or sitting in back row. Renualt is a new brand, so we cannot say too much about its reliablity. Kwid looks much smarter then maruti alto. It looks like suv from front.
