I’m really impressed with the practicality of CNG cars, even though they require compromising on boot space. But why are there no automatic variants in CNG cars? Please correct me if I’m wrong, in case any models are available. Is this because of the power loss in CNG mode?

The Maruti Suzuki Dzire is an excellent, comfortable car that's more spacious than the Tata Tiago, and has a larger boot too. Its engine is smoother, more refined, and more fuel-efficient, and being a Maruti car, your after-sales experience is also likely to be relatively fuss-free.As your first car, go for the Dzire. Its overall user-friendliness and its more premium experience will make you feel like you've spent your money well.

The Maruti Suzuki Celerio is a good option to consider. It is spacious, comfortable, and easy to drive. The 1.0-litre petrol engine is peppy and efficient, and the car is also available with a CNG option.The other option is the Maruti Suzuki Wagon R with the 1.2-litre petrol engine. It is good on space, comfortable for the city, and highly efficient too. The ZXi variant will fit in your Rs 7 lakh budget.

The Skoda Kylaq will be the perfect choice for your requirements. It has a punchy 1.0-litre turbo-petrol engine and is available in both a manual gearbox and a 6-speed torque converter automatic.The Kylaq has compact dimensions and has a well-balanced chassis that makes the car great fun to drive. The handling is particularly impressive, and it has a good build too. The Prestige variant in manual guise will fit in your budget, while the Signature+ AT variant works if you prefer the automatic.

For city use among the bikes you're looking at, the top two would be the Royal Enfield Scram 440 and Harley-Davidson X440 T. These bikes have large, long-stroke, single-cylinder engines, which will have the edge over the smaller 350s you're looking at. However, if most of your usage is inside the city, we'd recommend sticking with the 350cc roadsters from either Royal Enfield - Hunter/ Classic / Bullet - or Honda - in the form of its CB350 trio. These bikes will have more than enough grunt for city traffic and will also return more fuel economy. Take a test ride of these to see which one suits you best.
