Is the Hyundai Venue CNG worth the compromise in boot space?

There’s a factory fitted CNG kit that occupies a huge chunk of boot space. This can be a major issue for many potential buyers that often need to carry luggage or groceries. The loss of boot space is too big a sacrifice for a compact SUV, say some, while others argue the fuel cost savings and lower emissions justify the loss. The argument is usually about whether the CNG variant makes sense for city dwellers with limited driving requirements, or for someone who needs to be more versatile in their vehicle. Furthermore, it is discussed about how this compromise impacts utility and value proposition of the Venue CNG vis a vis its petrol counterpart or other CNG options available in the market.
