My new to me 2011 335D

My friend has the same year and model. The gas station shots mine is the one with top roof rack. 1st pick is once I took them off.

It has 120k miles, clean title, 2 previous owners. The only issues were glow plug, 1 injector needs replacement and engine mounts. I also went ahead and ordered air filter, oil change kit, transmission kit and downpipe.

What should I do next?
