AA0860 – 2003 BMW Z4 ROADSTER 2.5i Part Out

This 2003 BMW Z4 convertible has been dismantled, all the parts are cleaned, tested, and shelved, and are ready to be purchased.


We had high hopes of fixing this one up to resell it, but in the end, we decided to part it out due to some common but expensive problems found with the convertible top.


As of this time, we’ve dismantled a total of four BMW Z4’s, so if you’re looking for used Z4 parts, we probably have what you need.


Information regarding this ’03 BMW Z4


In the 2003 model, there were two engine options for the Z4, the 2.5L, and the 3.0L. This particular BMW Z4 we dismantled had the 2.5L engine paired with the 5-speed MANUAL transmission.


The MSRP on the 2003 Z4 Roadster 2.5i was $33,100, making it one of the cheaper BMWs to own. Only a few of the 3-series model Bimmers were more affordable that year.

The ’03 Z4 2.5i is the slower of the two. It has a 0-60mph time of 7.9 seconds. In contrast, the 3.0i Roadster goes 0-60 in about 6.5 seconds.


The top speed on the 2.5i is 146 mph (according to BMW). The 3.0i is said to get to 155 mph.


What engine is in a 2003 BMW Z4, and how much horsepower?

They made two different engines that year: a 2.5L 6-cyl (184 HP) and a 3.0L 6-cyl (225 HP) engine.


How much is a 2003 Z4 worth?

It will depend on its condition, how many miles it has, the different options, and engine size. 


As of late 2021, the KBB for the 2.5i version ranges from $5,500-$9,000.


The 3.0i will range from $6,000-$10,000.


Are there any BMW Z4’s with All-Wheel Drive?

No, ALL BMW Z4’s come with Rear-wheel Drive. There is no option for any other drivetrain.


Is it worth buying a used BMW Z4?

They are surprisingly cheap to buy compared to most BMWs, and I can see the appeal if you don’t need space for more than two people and are using it more of a secondary vehicle than, in my opinion, it’s not a bad choice. 


Be mindful that just because it’s a “cheaper” BMW doesn’t necessarily mean you will get the replacement parts for cheaper. As vehicles age, part manufacturers discontinue many parts, making the used parts market the only source for parts. While you may find some reasonably priced, some will be astronomically high due to the demand or scarcity.


It’s something to consider. 


It’s a good-looking car that performs well, might even achieve classic status in the future.
