Recommendation for purchase C30?

After I’m very satisfied with the Xc 60, my sister is thinking about buying a C30. The Volvo dealer of my trust told me a good 1.5 years ago that the C30 is selling very badly, because it’s just too expensive. What does it look like right now? The C30 speaks imho: + Consumption + Design + Volvo Image – Price – and? What are the alternatives?
