This is the all-wheel drive Mercedes Bluetech. It is a diesel. It takes DEF. The car has a power steering pump that is going out. The power steering pump is readily available on Pelican Parts. I bought this for my son and he was going to fix it but ended up with another vehicle. This is all wheel drive and has lowering suspension so it doesn't have a tow hitch. Come see it, it is a good car with some work.
