Not had personal experience of fixed price servicing, bit I read on here that dealers can be sneaky as to what it includes. i.e. not brake fluid and I doubt any parts, could be wrong. normal oil and filter change is around £100-£160 anyway, depending where in the country you are. so £299 for 2 years isn't much of a bargain if it is just oil and filters, you are just giving them their money early.
