What affects its junk value
- Age: at 23 years old, most of a 2003 Z4's value comes from reusable parts and scrap metal, not resale.
- Weight: as a two-seat sports car, it weighs less than a truck or SUV, so its value leans more on parts than on scrap weight. See how scrap prices by weight work.
- Catalytic converter: like all gas and diesel cars, it has a catalytic converter containing precious metals, one of the most valuable parts on a junk car. An offer assumes it's still in place. More on catalytic converters.
- Recalls: NHTSA lists 4 recalls for the 2003 Z4. Open recalls don't stop you from selling or junking it.
- Known problems: owners reported the most issues with the steering, typically around 43,000 miles. If that's what failed on yours, it can still be sold as-is.
2003 BMW Z4 recalls
NHTSA lists 4 safety recalls covering the 2003 BMW Z4. Open recalls don't stop you from selling or junking the car, but check your VIN at nhtsa.gov/recalls to see which apply to yours.
On certain passenger vehicles, under certain environmental conditions, a vapor lock in the fuel pump could occur causing the engine to stall. If this were to happen, the engine would not be able to be restarted for approximately 15 to 20 minutes.
Risk: If stalling were to occur, the driver would be unable to maintain vehicle speed or accelerate, increasing the risk of a crash.
On certain vehicles equipped with 18" tires, it is possible that the tire has been damaged during the mounting process to the rim.
Risk: Consequently, a loss of tire pressure, or a tire failure, could occur. Depending on traffic conditions and the driver's reactions, this could lead to a crash.
On certain passenger vehicles, the connection of the safety belt buckle to the steel rope of the tensioner does not meet BMW specifications. In severe frontal crashes, this connection can detach.
Risk: If the connection detaches, the protection provided by the safety belt is likely to be impaired, and serious injuries to the driver and/or front passenger could occur that might otherwise be mitigated.
