Firstly, I think we have the same size undies, I love the seats and once in them you don't want to get out,it is a pain getting in and out that's why mine isn't a daily, but no aches and pains. I believe the lights,idle,chirping issues have all been resolved. Mine is a mid 13 model and haven't had these problems.Can't comment on my tail lights though as I changed them and they never saw rain prior to removal.But that's a warranty issue so don't stress over it. But definitely go for a drive just to get a good feel of the seats... Enjoy your new car ;)
