I went through the normal ball joint, cracked manifold, brakes needed servicing etc issues early in my ownership - on a low mileage 2010 year 200.
So miles isn't everything with these cars and a record of good servicing possibly more important.
Then again - you can always be unlucky however hard you try to do your homework.
Bottom line is though - like you- mine makes me smile every morning I jump in it.
I've been in a company car since last Sat and I CANT WAIT for Clio time tomorrow now
Good luck with your box issues and getting sorted.
