Welcome Crocket...As you can see I'm about as far away as anyone can be but I can help you a bit (I'm that sort of guy
)
The TPMS valve issue is fairly common if you search the forum you will find various suggestions on how to limit the risk.. A knock in the back for cars made in the European factory is more common than than a knock in the front.
The door handles coming off
is very rare!
and there are quite a few shades of blue worldwide but only two in the UK according to your website...

Some countries get a dark navy blue, We used to own a moonlight blue (now discontinued) and as well as Vivid Blue in Australia we get Sky Blue and Clean Blue (which are fairly similar to each other and both a bit lighter than Ice blue..
Edit: If you browse the picture galleries on here you should find an example of each colour or you could wait for my upcoming Youtube slideshow which should have some shots of ever colour I think...
