Anyone have any advice on buying a 2015 320i

Due to my old Hyundai being totaled, I am now found looking for a used car.
They seem affordable, but I am nervous about how much money it will cost
to actually own this particular model. I've heard everyone and their brother
say that BMW's are cars that breakdown often and are expensive to repair,
but the people with these opinions have never actually owned one. The one I
am looking at has 40k miles, 2 owners, no wrecks or damage, and has a
very good track record of routine maintenance. If you all would help me out
with some insight I would really appreciate it.



Also, if anyone has any particular things I should be looking for that would be
red flags when I go look at the car in person, please let me know.
