My BMW started shaking on the highway and I need honest advice

[josbuttler]

I'm writing this because I genuinely don't know what to do anymore and I'm hoping someone here has been through something similar. I have a BMW 520i that I bought used about eight months ago, and for the first few months it was an absolute dream to drive. But for the past two weeks, every time I go above 100 kilometers per hour on the highway, the whole car starts vibrating like crazy. It's not a small shake either – my steering wheel wobbles, my seat vibrates, and honestly it's scary because I feel like I'm losing control. I took it to a garage near my house in Mussafah and the guy balanced the tires and charged me 150 dirhams, but the problem is still there. Then he said maybe the alignment is off, so I paid for that too. Still shaking. Now he's telling me it could be the suspension or maybe the axles, but he doesn't sound confident at all and I don't want to keep throwing money at guesses. A friend told me to check www.800sayara.com/bmw-repair-abu-dhabi/ because apparently there are specialists who actually understand BMWs instead of just guessing like my current mechanic. I'm not a car expert by any means, so I don't know if this shaking thing is dangerous or just annoying. Has anyone else had this problem with their BMW? What was the actual cause when you finally got it fixed? I use my car to drive to Dubai for work three times a week and I'm genuinely worried about safety at this point. I don't mind paying for proper repairs but I want someone who actually knows what they're doing, not someone who keeps trying random things and hoping something works. Any advice would really help because I'm losing sleep over this.
