After you drive a car for a few months, it can be used or new, you know that one day a message is going to appear on your computer screen saying "change the lamp or check the tire pressure or worst the battery can be gone, or the electronic system half is not working, anything may happen, you have to be prepared because you cannot prevent all the things.
I am very proud of all the purchases I've made as I didn't have any major problems with the vehicles I drove. The regular maintenance is very important so when I buy a car, I will ask about all the records the owner has, but as I said above, you never can prevent some things from happening so this is what went wrong with the following series:
BMW 745li- Engine Vibration- I experienced that because I used regular gas instead of premium, so the filter got stock. The new models of 7 series have a sensitive fuel system requiring a concrete level of pressure and components so it is very easy to disturb it if the norms are not respected.
BMW-525i- Transmission Issue- I felt a turbulence while transitioning from 2nd to 3rd speed.
BMW 530i and very commun to 3 series as well- Break Pads SQUEALING- I've had that issue with one of BMW's and this is the white one you saw on my first posts. It started to squeal loudly right away and after I replaced them, I had a headache hearing them again, I thought it was a rottor problem but I still didn't figure it out. Plus the 2 front wheel drive is very unsafe to drive in the rain or especially snow, it is very playful when it comes to the cold season.
Besides that, the BMW is the best for its design, performance and capacity. It is fun to drive and yes it is a "head turner" :))
