I wanted to purchase car my budget is only 4 lac please suggest
If you were to look for cars basis price (Ex - showroom prices) between 3.90 lacs to 4.10 lacs, then you including each models variants around 43 cars to choose from:
Alto 800, Alto K10, EECO, WagonR, Estilo and A Star from Maruti Suzuki
Eon, Santro and i10 1.1 from Hyundai
Brio from Honda
Beat and Spark from Chevrolet
Figo from Ford
Xeta from Tata Motors
If your budget is all inclusive (on-road) then cars that will go out from the basket mentioned above would be Figo and Brio completely. Top to mid-end variants of other cars.
It's better you narrow your basket of preference further to not more than 2-3 cars , this will help you to avoid confusion and take a more thought through decision.
You must however, take exhaustive test drive of the last 3 cars that you shortlist. Also define your need from the car.
You must always remember that on an average the difference between ex-showroom and on-road is around 12-14%. On-road price will always be higher than ex-showroom price. Define your budget accordingly.
