What are the colours available in Maruti Swift?

Ford freestyle has the least maintenance with high safety and build. Grand i10 nios is another good option with a slightly higher maintenance and so is swift. In my opinion, you should not worry about mileage with your usage being minimal. Give priority to safety, build quality, comfort etc

The structure and the sheet is of metal whereas the cabin still very much like other Maruti Suzuki cars in terms of the plastic quality and materials used.

Yes, only in top variants. The swift comes with a 2din audio space in the dashboard, hence you can fit a 7" multimedia player with reverse camera in any variant as an additional accessory... any time.

No but it can be easily installed from after market with a cost of 10500/-. only. Remember recommend RD company power windows as it is better than autocop
