5500 kms, no rattles at all. Maybe a tiny squeak from the gear lever when it goes left, but that's it. Very satisfied with the quality and finish.
It took me quite a lot of time to get the perfect seating position too (and I'm still not 100% sure I found it). I'm quite demanding when it comes to seating position - 6'3" and a history of back problems made me very picky and Volvo seats are probably the best in class when it comes to comfort. So far so good, and that's coming from an Alfa which I could drive for ten hours and step out fresh and without a trace of back pain.
Interestingly, part of my lower back problems seems to have been caused by car seats. I spent a small fortune on chiropractics, until my chiropractor told me he had another patient with exactly the same problem as mine. Guess what? We both drove Astras! Got rid of the Astra, never had lower back problems again! After that experience, it's hard for me to underestimate the importance of car seats.
Oh, and LHD V40s do have a footrest. Sorry to hear they couldn't squeeze it in for the RHD version. Alfa Giulietta has the same problem.
