Volvo V70 purchase advice

Hello, I’m new here and looking for a new vehicle. The Volvo V70 is the first choice for me in space, because I need a big station wagon. And what you hear is that they are quite durable. What do you think of this natural gas vehicle in particular? What are the experiences compared to diesels in terms of cost? The litre costs are lower in terms of natural gas, but the consumption is also higher. Another advantage of the natural gas vehicle would be that there is also a green one. Environmental badge has. Unfortunately, this vehicle has no cruise control :-)( Thank you in advance for your tabster tips
