Quality comes first with VW. More safety and excellent riding comfort are extremely different from others. It will be brought into the best in segment if it would have less engine noise, and more power delivery. About milage, it depends on your drive with an untuned engine. Keep in a feather flow drive to bring above 20kml. All about petrol 1.2L HL+ only.
Worst thing is about service only. They don't even have a common respect to customers, i had worst experience with VW service Kollam, Umayanalloor, Kerala, India.
