Yes in many aspects the UX is a poor design for any car of that size let alone a premium brand. My current car, a Kia Niro is actually slightly smaller than the UX but manages a larger boot and substantially more legroom in the back. Better economy than the UX I think as well, around 60 mpg on average.
Despite this I have on order a UX Takumi, most of us buy cars on the basis of desire over ruling logic in some circumstances.
I remember back in my youth I fell in love with a Wolseley , something like a 14/60 model I believe and why did I want it, because it had an illuminated badge in the grill. Sense prevailed in the end, it was a bit of a tatty old thing.
I have bought several cars in the past that are legendary for the mirth they cause in the motoring press, Austin Allegro, Mini Metro. I have to say that the Allegro was a reliable comfy car, superb 1500cc Maxi engine. Metro gave me stirling service over many years, amazingly roomy for such a small car, took us with two grandparents and our baby son on holiday, pulled like a train towing a small camping trailer.
So there we are, hope I enjoy the UX when it turns up.
