I understand, it's not easy for females especially to go in workshops etc every now and then.
however, a lot of workshps in Lahore (if you are from Lahore) like Autospot.pk, etc. offer home pick and drop of your cars and they fix every issue all under one roof.. however, it is still a hassle.
For females though, i think ALTO VXL AGS would be the best choice due to firstly it is automatic, it is compatc in size, it is very spacious inside according to its category, and fuel average is the best in currently avaialable cars in Pak (18-20 km/L) plus resale is super hot ... and it would be in a lesser price than Cultus.
however, as you asked for AC performance and mileage of Cultus, the new cultus gives the second best mileage in cars available in Pak and AC is also good.
