You will not find many used BMW and Audi cars (hatchbacks) in India because very few were ever sold.
BMW did offer the 1 Series hatchback for a short time, but the numbers were still limited.

Instead, it’s better to explore their small SUVs like the Audi Q3 and the BMW X1. If you are open to Mercedes-Benz cars, you can also check the A-Class or B-Class hatchbacks, though these too are rare, or consider the Mercedes GLA. 

When buying a premium used car, though, make sure you buy from the brand itself, as they all have an approved used program. You can also buy one from a very reputable reseller, and if things go wrong, it can be very expensive to fix. 

The Volkswagen Tiguan R-Line is enjoyable to drive but is undoubtedly expensive. Regular maintenance should not be a problem, but the availability of parts could be an issue in case of accident repairs. Expensive imported cars also typically do not retain their value unless there is special market interest.

As an alternative, consider the Skoda Kodiaq, which is essentially the same car underneath but offers more features and a generally plusher interior. Parts availability will also be better for the Kodiaq.

If driving experience is a priority, the Audi Q3 is also worth considering. It may not be cutting-edge inside, but it is engaging to drive with a strong petrol engine. With the next-generation Q3 expected in India next year, you could push for big discounts on the current model.
