These are Gamma engines and chain drive. A correctly specced oil is therefore very important.
2015 to 2021 is 6 years and that will be a full service (the timings are in the handbook if that helps).
Note they don't include the pollen filter and use it as an opportunity to upsell (about £35) as the service schedule in the handbook is a check and replace rather than a replace. 6 years should also be brake fluid change but depending how good your dealer is they may just suck out what is in the brake reservoir and replace that as it saves them time on the bleed procedure. If the bleed nipples are dry and dusty when you get the car back, chances are they won't have done it (it is a really common miss amongst all Marques btw as if they strip the thread / break the bleed nipple due to corrosion, its a new brake caliper which doesn't go down well with the customer). If its been serviced properly beforehand, it shouldn't be that bad though.
It should also be a fuel filter on 6 years and again because its a messy job, some dealers miss it as you won't know until fuel delivery starts to stutter in about 4 years time. If unsure it has been done, ask to see the old one.
Not all dealers are bad though so hopefully yours is a good one. The forum is 50:50 on good and bad dealer reviews.
