The worst car and company in my experience

Look and Style of the car is ok when Nissan comes for maintenance or service, the charges they quote, comes to almost the expense of benz car . ground clearance is very pathetic, no pick up while in high range.Mileage, when compared to the new cars is just ok . I'm a nissan owner , and my Nissan hit a bit in the under of the vehicle, and took to nissan service centr , the expense required for it, that they said, was tremendously shocking.( 2,80,000 ) . then just imagine if it was a big accident...don't tell me they will quote a 20 or more lakh for that .? I feel nissan is putting themselves down by this so I advise all car users not to go nissan , because I have used so many cars, but this is the worst experience in my life.
