I bought my 2005 330ci ZHP (build date of 8/2005) in August 2010. It was dang clean -- from engine to interior.
The previous owner did a great job of regularly changing the oil and other fluids. The previous owner bought the car new and paid cash (about $45,000). I was also a cash buyer, so this car has never seen a lien on its title.
The car was equipped with leather seats (natural brown), leather M steering wheel, black cube trim, and factory navigation system.
