I bought Emma a Countryman last October, its an amazingly good car - the 500x really has some to go to beat it. We were very anti-Countryman before, we then had a top-spec Cooper SD for two weeks while my BMW was being fixed. There is an amazing amount of space in it, it's incredibly albe and after a hefty discount was applied very reasonable
Saying that, we both quite the 500x... We'd need to see it in the flesh to say for sure, but it looks quite nice.
The rear profile definitely reminds me of the Mito though....
