BMW 8 Series review

The 840d is obviously the one for company car drivers, thanks to the 160g/km CO2. The M850i is 228g/km, still good beside its rivals.

But fuelling the 8 Series isn't too much more costly than far cheaper cars. Whereas the depreciation is in a higher orbit altogether. And while some new cars above £100,000 start out in short supply and don't depreciate at all in their early months, it's unlikely the 8 Series will be so lucky.

Best then to hand the depreciation risk to BMW by going for PCP or lease. The initial quote for an in-house BMW PCP for the 840d xDrive is £25k down and £876 a month over three years at 10k miles a year.

As usual if you're buying it using your own money, look at BMW's good-value servicing packages. Warranty is three years/unlimited.
