I have An 11-year old e90 325i. It has only 67,000 miles. I decided to keep it when I bought my 2015 528iX, and I gave it to my teenage kids to drive to school. Now I'm trying to decide if it's time to sell it. I've had to replace the following items over the last three years: belt tensioner, valve cover gasket, both right and left rear window regulators, and water pump and thermostat. So my question is this: what's the next well-know, expected repair on this car?
