When I first bought this car, I had a mechanic look over the car and this is what I got back. I’ve had something fixed with the car and others not so much.

Somwtimes when im driving I feel as if I’m floating, like all my wheels might not be touching the floor. Now when I tell others to drive my car they tell me it’s fine. I went to a mechanic to change my brakes, and he inspected it and said they were fine. But when I go to brake, I hear it squeal. Driving me insane. And another thing was when they put my car on the lift, one tire was hanging down further than the rest, might be something about a lower ball joint or bar link I was quoted $500. My car drives rough, or maybe it’s all the damn potholes in San Diego, either way I would like to make it smoother if possible. I wanna know if maybe because I am a female with no auto mechanic knowledge, are all these prices accurate. I really try to understand what and how makes a car work, and it’s difficult. With my knowledge I know I should be pedaling. Lol but any input would be appreciated.
