I purchased Mehran vx limited edition in 8.40 lac 3 days before for 3 months use maximum as I have already booked alto AGS. The zero meter car's wheel alignment is not proper and car is drifting towards left, secondly on ac it is just giving 12 km/l average. There is vibration or bumps on plain road, hard gears and hard brake. What should I do for smooth drive plus best fuel average?
