Hi, so I've had my '16 535i for almost a year and a half and I was thinking about looking for a way to get more power. I've been thinking about upgrading to a '15/'16 M5 for a while now and I've been conflicted about just saving my money for a couple years (2-3) until I can afford to get the car and get the basic maintenance early or tune my current car with either bm3 or mhd with some supporting mods to come in the next couple months. My car is currently at about 134k miles.
PS. This car was handed down to me
