Welcome to AM ownership. I agree with everything you said, however I guess I got more lucky with the seats, no problems here. No one else complained either, but maybe they were just too impressed by the rest
AM and Porsche are different, one is not better than the other, just depends what you look for. Considering how fast you can/should drive on public roads, I'd rather loose a little performance but have a more unique ownership experience, quirks included
Lovely car you got, enjoy
