So what you are saying is that a first year apprentice who had little to no clue did the servicing on your car prior to you owning it? haha.
That's pretty dependant. Depends on the age of the car, variant and what needs doing.
When I was an apprentice at Jag, I used to get all the old, low km ones that just needed a basic oil and filter change. Or I'd get a new one, but only if it was for stuff like doing software updates and whatnot (not much on the mechanical side).
They wouldn't let me near the "R" variants.
I've seen this at most Dealerships. The apprentices get the old cars, while they give the Master Techs all the new top of the line stuff.
