Car Shopping Alone

I currently drive a 2017 Audi Q3, and it's starting to have oil consumption issues which apparently is common what it hits higher mileage...it's got about 87k on it now.

I'm looking at a 2018 all road in a dope green on Saturday, with like 19k miles, it's super low. I love the wagons.

Problem is I've never gone to a dealership alone, usually with my dad or husband. Neither are available. I'm worried they are try to screw me over as a female going car shopping alone.
