Car is good but poor Mileage in A/C and expensive service charge ...

Look and Style of the Car is really good. I just completed 40000 Kms and comfort of the car is also very good. The pickup is good without A/C. We can feel the performance going down when we switch on A/C and the mileage too. With A/C on highways you will get around 14 Kmpl which Ii was expecting around 20KMPL when I bought the car. The car is worth for the money when you buy but the service charge is very costly. Every time I give the car for service I used to have a bill around Rs 4000 and recently when I gave for 40000 Km they gave a service estimation of Rs 6000 . Labour charge for a service in Hyundai will itself comes around Rs 2286 Tax extra. I'm not sure whether it vary according to dealer. I serviced in Popular Hyundai Cochin. Overall experience the car is good for a small family but the service charge is too costly for a budget car.
