[m550ilover]

I recently purchased a m550i the car had 650000 miles on it. I went too put a full tank of gas in it the fuel level was showing around the last 2 bars but had 100+ miles left I was only able to out in $30 dollars worth of gas u till the pump stopped as if the car was full I kept trying to add more gas but it kept stooping and small amounts of gas will drizzle out of the tank on the inside the car is only at a half tank there no lights on the dash or any fault codes pop up is there anything you guys know about this or could help me I want to have a general idea of what’s wrong with the car before I take it in for servicing. I also tried multiple gas stations before u recommend that
