Servised my car to a non dealer

[bmw5]

I recently visited a bmw dealer for my 2007 X3 159000 kilometres as i was hearing a metal noise from the front left wheel.The chief mechanic told me i had to change front and back discs and rear pads with a total cost of 550 euros, 400 for the discs and 150 for the rear pads.I left and visited a store near my house and changed the rear pads for 50 euros! i asked for a price for the rear and front discs and was told 170 euros ( at bmw 400 euros).
The mechanic had a closer look and spent a lot of time inspecting the car and it needed brake fluids (in very bad condition), new engine and cabin filters, for a price of 44 euros!
It seems that the car also needs new wishbones ( a part not the whole unit) as in braking the steering wheel isnt steady at a price of 160 euros OR new front and rear braking discs.Lesson learned: in older and high mileage cars, find a mechanic to thoroughly inspect your car.

Highly agreed. I've taken mine and my mom's older bmw to various mechanics and indy shops locally (unfortunately, not too many or most reliable apparently), and they've done nothing but misdiagnose issues, forget to put parts back, and just be generally worse off than before bringing the car to get serviced. I've resorted to just doing evrything myself (within reason) for this exact reason. Their asking prices alone will kill ya!
