What are peoples thoughts on the 8 series?
I had one for the past year, covering about 12k miles. An 840i Coupe, late 2020 in Tanzanite Blue - lots of spec. I have changed it for a 5 Series mainly for practicality reasons, as well as the values dropping. The BMW dealer I sold it to actually made a loss on it, and WBAC were offering £12k less than they gave me (though their prices have dropped a lot lately for most cars).
It was a great car and never had any issues (aside from horrible squeaking brakes that seem to plague a lot of BMWs), it looked fantastic and drove well, but it's a large car and a cruiser, don't think of it as any sort of sports car. Ride quality is ok, but it's firm enough in comfort mode and sport etc is just pointlessly firm. Thin tyres on 20's don't help here. In terms of comfort and refinement, my previous 7 Series was much better.
The first thing to note is that the Coupe looks better (to my eye) but is very much a 2+2 at best. You can cram 4 adults into it but you won't be able to drive far. I saw it as a 3 seater, as the passengers on the passenger side can squash up a bit, but there's no head room in the back at all.
Another unusual thing is the width, it's one of the widest cars you'll find on the road and with the big doors, it can make parking a bit troublesome. The Gran Coupe has smaller doors but is still very wide.
The LCI model (2022) has minimal changes. The front grille lights up and has twin slats, and the main interior screen is larger, but does look a bit awkward. There are a couple of new wheel designs too, but that's it.
In terms of things going wrong, it's mechanically very similar to something like an M340i, less so in fact as it has no xDrive system to go wrong. I would imagine a lot of the electrical systems are the same. Of course this can depend on spec, if you have Laserlights for example, replacing one of those would no doubt be a huge expense. Or if the Driving Assistant system packed up. The warranty is stupidly expensive and formed part of the reason I changed it too, you're probably better off just risking it, but that's a personal decision - it's gambling vs insurance, effectively.
Coming onto the spec, mine had a lot, Laserlights, B&W Audio, Driving Assistant Pro. I'd say they are all worth it but not a must have by any means. The standard lights are still adaptive and the Lasers are perhaps 10% brighter at a push. The B&W is better than the standard HK but it depends how fussy you are about audio. The ventilated seats are meh, they are not cooled (like a Range Rover), but do keep your back a bit fresher when it's warm. If you're often on the motorway as mentioned, Driving Assistant Pro is brilliant, but it's very dodgy on winding country roads and you'll have to carefully monitor it. HUD is standard.
All in all I would definitely recommend it, it's one of the nicest looking cars you'll come across and people do tend to show an interest in it too.
