Toyota Corolla has always been an instant success as with this car you don't have to think too much about the reliability as Toyotas have always been Rock solid with the reliability and plus the fuel economy is also good for a car of this category.
If you're planning to buy a sub 25 lakh car, don't think twice as with other cars like Octavia, the performance is good but you don't get that peace of mind as the reliability isn't that good but with the Corolla the interiors and exteriors are not that flamboyant but the quality is very good and still feels like a new after years of diriving with minimal service cost (7-10k per service) and that too with very few major issues.
