The first major safety issue are the side mirrors. They are not big enough so it's better if you have Blind Spot Monitoring System. The other thing is the rear camera. It comes with the nav system /and Full Link at some point/, the nav is pretty useless compared with Google Maps, but the backup camera is a must. You cannot see enough with that long car. And as it is tall you might miss a kid or even a low car. It went over my budget and i did not think that the rear camera will be so needed. After six months I installed a Dual dash cam, that has a rear camera and it can be shown on the main camera screen with the push of a button. I use it like every day. Bi-Xenons are a great. I have it and it's a joy to drive in the dark. Even on a country road, they are curving quite nisely.
You can get the sporty seats, they are not leather, but have alcantara center and heating, and have more bolstering then the normal ones, and lumbar on both front seats /electric for the driver/. Also at some point the sport seats came with heating window washer nozzles /a part of heating package/. They are a lot cheaper, still comfortable but miss on a memory seats and passenger mirror automatic
lowering /this can be programed later on/. Nice compromise thow. I did not get the electric doors, because they come with the keyless entry. I do not like it. I kind of regret that, because I would really benefit the electric doors sometimes and I'm sure there is a way to disable the keyless system from the computer. 17" wheels are more suitable for high speeds. It makes the car more stable /here the speed limit is 140km/h - 87mph and it is noticeable/. If it's mostly town you do not need them. The 18" are just a waste of money, the car becomes uncomfortable, and you will need the suspension upgrade. Tyres become more expensive and wheels are more prone to damage.
