My KIA Caren’s (current car) was serviced at one year with 5,000 miles on the clock.
Don’t think they did anything to it other than check all the nuts and bolts were still tight.
I think the service went something like this… I turn up with car, they take the car around the back, out of sight from me while I wait, disconnect my cars cameras, sit down playing cards for an hour while drinking tea then after 90 minutes bring the car back around the front telling me the cars in good condition and all’s OK.
Service booked stamped and everything is fine for any future buyers of the car.?
