Advice on oil level and BMW car prep

[GT TWO]

Guys

as you know I picked up my baby and the handover seemed good, the sales guy was really nice etc etc.

I had a question in my mind over the way the car was prepped.

I wanted the car in the showroom so me and a pal could go over it before driving off.

I noticed the rear offside tyre was really low on air... how could such an obvious thing be missed? This caused me to question the level of care put into the prep.

I was excited about the car so told the sales guy as the techs had all gone home I would drive a mile to the petrol station but if the tyre had a slow puncture I would want new rears..... all fine.

I get home and I notice the oil level is 0.5, should it be more for a car leaving the showroom?

Last night the low oil warning light comes on... I was on a hill so I am not sure if this would cause it?

Just off to get some TWS in a mo from my pal who is a BMW master tech but I am concerned they have not put the required effort in.

What do you guys think?

Cheers
