2004 BMW 3 Series

I’m looking to sell my 2004 BMW 325i. Rear wheel drive. It was my daily until it created a knocking sound and I stopped driving it. It runs and drives but I recommend to tow it, it’s not a usual sound but goes away after a few minutes. 2 sets of tires. Winter tires have 1 season on them. No leaks. Back up camera and dash cam included. It also has a remote starter. If you could get it fixed, it’s a very fun car to drive. Otherwise, it’s a complete set of spare parts. I could start it, but no test drive. Asking 1500 obo.
