I've seen a video, suggests oil is due June 2021, front and rear brakes are in 3200m and the last service was 16,000 miles ago in June 2019. Everything is Green "OK".
It is seemingly hard to find the service intervals for an F10 - other than they are variable. That suggests this being serviced annually, after only 4k miles each year up to 2019 seems excessive! Then a big jump 2019 to date
As Dave says the 3200 mile brake thing means the useless distance estimator has reached the point at which its waiting for the brake pad first stage wear sensor to trigger. They are notoriously rubbish - I bought my car with 5k miles on the clock at 11 months old and the brake pad life indicator has NEVER worked. At the cars first service on 15k miles it said I had 3200 miles left - the reality was the pads were not even half worn. The dealer reset it for me.
The service scheme is as follows:
Oil Service
Oil Service + Air/Fuel Filter
Oil Service
Oil Service + Air/Fuel Filter
Oil Service
etc - with either 2 years or variable mileage of up to around 20k between each one. Additionally, a Vehicle Check service is performed every 38k miles.
Strangely tempted by that 5. Full BMWSH, iDrive showed it to be recently service, tyres looked good and I would drive away with 1 years warranty and a fresh MOT. If I could knock them down closer to £14k, that puts an interesting spin on it regardless of the age (and it's a 535d)
Someone tell me I am being daft and only being tempted by the convenience...
My first F10 was a 2010 530d SE - a good spec launch car. When I went to replace in 2016 it my shortlist came down to either a 2013 pre LCI 535d M Sport or a 2015 LCI 530d M Sport. I went with the LCI and absolutely do not regret it, IMHO its an improved car over the pre facelift in loads of really subtle ways which sound trivial but really add up. There is absolutely no way I felt it worth missing out on that for the sake of an extra 50bhp and to be honest it isn't like the LCI 530d is slow - it'll hit 62mph in 5.8 seconds, after all. I never find mine wanting performance wise, it is always quick enough in any situation I find myself in.
Also, that 535d is 9 years old. £14k is a lot of money to spend on a car thats rapidly heading towards being an 'old car' with all the fun and games that goes with that.
I wouldn't even consider that 535d - the 530d you posted is a better car and you can purchase a years BMW warranty for it for just over a grand which - whilst a LOT of money - gives you almost the same level of coverage as you'd get on that 535d.
