My personal suggestions is to avoid Suzuki cars.
Honda Life is the best car in the list due to excellent fuel economy, comfort, and reliability. But before buying this car you should find out if the spare parts are easily available in your area i.e. Gujranwala.
The next best car is Honda City iDSI-2004 but only if you can afford the higher fuel average.
Honda City EXi 2003 is better looking car and fuel average is also better than iDSI. But personally, I would go for a newer model City.
