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.

If you want a 650cc bike that can be used daily, the models at the forefront are the Royal Enfield Interceptor 650 and BSA Gold Star 650. Both have torquey engines - albeit ones that sound and behave very differently - with upright ergonomics making them a good fit for daily usage. Do bear in mind that both bikes are much heavier than your current Honda CB350 H'ness and will demand some caution before you get used to their size and heft.If you want something a little more unique, then the Kawasaki Z650 or Z650RS makes for genuinely usable big bikes. While their prices are more than double those of the Royal Enfield and BSA, they really are hassle-free, punchy, well-built machines that will serve you well for a long time.One thing to note with the Kawasaki 650s is that they have low ground clearance, which could be a factor that influences your purchase if your city doesn't have good roads.
