Should I Buy A BMW Used 5 Series ?

Sadly the 5 series is all looks and not very reliably. I have an 06 5 series too with navi and other packages, the navigation keeps going nuts and I have to bring it into the dealership to get it fixed twice already. Electrical problems with my headlights. and getting things fixed even a simple tire is so expensive on the car. But since it is certified pre-owned you won't have to worry so much about it since most will be covered. Just keep in mind that anything that needs to be fixed due to wear and tear it'll cost ya a lot. Maybe better to buy a brand new 3 series instead, but I hear the coupe has lots of electrical problems too.
