According to the worst 2015 car models to avoid the BMW 7 series has the worst resale value...
And I befriended a certified BMW mechanic in the last few months. He tells me never to buy BMW’s. This straight from a certified Beemer dude. His words, not mine.
I’ve owned three of them (still have one) and I agree. One of the most costly and difficult repairable lines on the market. Anything a mechanic has to do to a BMW costs a lot of money. On one model you literally have to remove the entire headlight assembly to change a bulb. And that required repositioning the radiator a little to get at the screws holding it in. Just terrible.
