I got my self dezire on Jan 2014, I am driving around 25 km per day, normally goes to office and come back from Noida sector 51 to Noida sector 144. I am very surprised to see my mileage indicator going high daily and now it is showing 19.8 and in fact it is giving too .
Everything of swift D is very good, from space to ride quality. The only problem I see is that gear shifting some times gives some issues.
