BMW Service plans

[Elroy Blue]

For my sins, I have an I4. Coming up for its 2 year trip to the dealer and I've been quoted £366 (for brake fluid and a cabin filter!!!!)
I was looking at the service plans and have an option of 'service inclusive' which is a £605 one off payment, which is for two services or a service plan which is a per month payment and totals £539 , which includes two services and some yearly 'checks'.
I can only assume that the four year service will be around the same price, they appear to be no brainers, and I can't see why you wouldn't pick the monthly option.
Are they the cheaper option they appear or am I missing something.

go with the plan, seems to be cheaper option unless you take it to a specialist

Or just book it with a specialist.

That price is outrageous for a brake fluid and cabin filter!

Just paid £50 for brake fluid change for my 3 series at ATS
