It is indeed a great looking car and kit that is second to none. The 3, ZS and HS aremiles apart from their predecessors, infact I believe the HS won car of year. The new hybrid+ makes 224HP and around 50mpg. It is indeed bigger than your xc40, being around 4.6m long.
Android Auto / Car Play, I believe is down to licensing, why it isn’t wireless. Hundai/Kia in the grand scheme of things, have only recently gone wiress AA & CP on it’s ccNC models and it’s not alone in this area. The latest car play ultra, has seen manufacturers like BMW saying they aren’t goin to support it. Many manufacturers are looking at integrating Android Automotive, with Google up front and Youtube, if you wish. That said, there are some excellent wireless adaptors for around £50 these days. @Rene mentioned one the day I think?
The Ski hatch, the thing I always forget and end up dropping half the rear seats, so like you said, it’s not a biggy.
