Depends on Spares like - common wear & tear items or replacement parts
> Brake Pads
> Headlights, Taillights
> Suspension Components - Lower Arm, Link Rod, Engine Mounts, Shocker Mounts etc
> Door Lock set
> Switches, Bulbs etc
> Clutch Plate Kit
were common in between Esteem and Baleno - Though both cars are discontinued - but procurement of items should not be an issue (even if original part not readily in stock - can be obtained through MGP Store or Workshop on order in 5 to 7 days)
However -
> Bumpers - are unique to every model. If bumper is damaged - it may take time to get replacement bumper as would be on order.
> Major Items like - Catalytic Converter, Engine Transmission will ofcourse take time
In terms of costing - may however witness a slight higher costing for discontinued models.
