I personally think that maybe a significant reason for the less than stellar sales of the Mirage is due to its styling. I think it is fairly decent looking. But it has taken a bit of time for the styling to really warm up to me. Yes I like it. However, I think the following is true.
It looks a bit too girly to me. And even though it is low in the h.p. department, a car doesn't have to LOOK like it is low in the h.p. department. I saw a VW similar HB drive by the other day. I believe it is bigger than the Mirage so not exactly apples to apples. But that thing *looked sporty. It "looks" like something that would be seen racing on a road course. And it has a more manly type of look to it. I think the Mirage looks kind of sissy. I still like it, but I'm not afraid to face reality (at least with the Mirage). That's part of why I call my car The Blueberry. It's a sissy kind of name for a sissy looking car.
Back when I was in automotive, there was a study done (I forget by who, but I don't think it was internal). People were requested to look at un-named vehicles (course anyone who knows cars knew every one in the pictures), and they were asked which cars they thought were more attractive. It was 100% clear, the cars that had a mean / mad / aggressive look to their front end (like the faces on the movie Cars) were always preferred over the cars that had a happy face. I forget which car had the happiest face, but it was completely crushed in this survey. It might have been an automotive magazine that did this study, I don't exactly remember. But, styling sells cars. Ladies want a car they feel give them a certain image, it doesn't matter if it has a V12 or if there is a gerbil running on a wheel under the hood. (Note: Not ALL women, but the vast majority don't care about the engine). And dudes prefer a car that at least has a sporty look to them.
I personally prefer a car that causes all the women to want to get in the car with me, and kiss me on the jaw. But I look like Shrek and smell twice as bad so that is going to have to be one helluva car.
And I'm sure I couldn't afford it if it existed.
