Analysis
What Problems Does the 2003 BMW Z4 Have?
Recalls have been issued for certain BMW Z4 models (though not specific to just 2003) related to the positive battery cable and fuel pump relay, posing a fire risk. It is essential to check the vehicle's VIN for outstanding recall notices.
Long-term reliability can be a concern, especially with the early model years like 2003. Regular maintenance and addressing issues promptly are crucial for preventing major problems. Models with higher mileage may require more extensive repairs. Specific to the 2003 model year, concerns regarding the initial production quality and potential for early component failures should be considered.
How long will the 2003 BMW Z4 last?
Over time, common weaknesses emerge, including suspension wear, oil leaks (valve cover, oil filter housing), and electrical glitches, especially with the convertible top. Neglecting these issues can significantly shorten the car's lifespan. The key to long-term durability is proactive maintenance and addressing age-related wear and tear.
What Technology & Safety Features are Included?
In terms of safety, standard features included anti-lock brakes (ABS), dynamic stability control (DSC) on the 3.0i model, and front airbags. Side airbags were optional. Driver-assistance features were limited compared to modern vehicles.
Crash-test ratings from the IIHS (Insurance Institute for Highway Safety) and NHTSA (National Highway Traffic Safety Administration) were generally favorable for frontal impact protection. However, it's essential to consider the age of the vehicle and the advancements in safety technology since 2003. The available tech and safety features were adequate for the time, but modern vehicles offer significantly more advanced options. The Z4 focused more on the driving experience than cutting-edge technology.

2003 BMW Z4 Prices and Market Value
Factors affecting resale value include: mileage, overall condition (interior/exterior), maintenance history, trim level (3.0i models generally command a higher price), and the presence of desirable options like the Sport Package or premium sound system. Low-mileage, well-maintained examples fetch the highest prices.

How Does the 2003 BMW Z4 Compare to Other Convertible?
Regarding reliability, the Boxster can have similar potential issues. The SLK and TT have similar levels of electronic complications. The Z4 offers a good balance of performance and value on the used market.
In terms of price, the Z4 often represents a more affordable option than the Porsche Boxster. The Mercedes-Benz SLK might be comparably priced but will offer less athletic handling. Similar alternatives include the Honda S2000 for more raw performance or the Mazda MX-5 Miata for lighter weight and cheaper maintenance. Consider the S2000 for reliability; consider the Miata for an extremely low cost of ownership.

Final Verdict: Is the 2003 BMW Z4 a Good Convertible?
It is more appealing as a used car than a new one. It's best for someone who wants open-top driving fun and appreciates BMW's sporty character. Just be prepared for the potential higher ownership costs associated with a used German sports car.

2003 BMW E85 3.0L 6sp manual M SportI've owned my 2003 3.0i 6sp E85 for almost 9 years. Equipped w/ M Sport option, 18" staggered alloys and painted in a beautiful Toledo Blue. Yes the car has need some maintenance, some worn parts replaced, but nothing too surprising or extraordinary expensive aside from tires. I'm in my 60's and still do most of my own work. Love the ride, the style, 6sp manual transmission, the power, the smoothness of the car in general. Would I recommend this car? Only to those that love a car that YOU want to drive. NO AI frills to distract one. Just a pure driving experience.

Best car I've ever owned!!!Where can I begin? - I first owned a 1968 Shelby 350, then went to Pontiac for their Trans-Am models until 2000 when I bought my first BMW 3 in 2000. In 2003, I completely changed brands to BMW with my Z4. 2nd Day of production, I was in BMW's factory in Spartanburg,SC to witness her birth. Afterwards, we spent our first moments together on BMW's nearby test track. After those all too brief moments, she was wrapped & packaged to be delivered to my dealer in AZ. The days I spent waiting in AZ seemed endless as I waited to bring her into my home. She now has a special space in my garage. It may sound somewhat anthropomorphic but BMW creates a product which becomes part of your life. Own a BMW and be prepared to have it become part of Your Family.

Made a mistake buying 2003 modelThe 2003 model, being a new design, came with many faults which I learned at 74K miles. Had problems with alignment, air cond/heater system, top did not operate electrically, tires worn unevenly, air bag sensor. I paid a premium price for this car and another 4K to get all the things repaired which I found after driving it a couple thousand miles. Mechanical costs too much for me. I lost a ton when I traded it.

The stock coils garbage. Replaced mine @70k kmLove how it handles now after upgrading to 18 inchers with Michelin Pilot Sports. It's a bit underpowered with the 2.5 but certainly adequate. Will still top out at 236 kph! Keep up with maintenance on these cars otherwise they'll bite you. Check forums for items.

FIRST CAR AND DON’T REGRET ITThis car is amazing for a someone who just wants to cruise & i put in a aux port & fixed the ac and other engine parts!

Best vehicular purchase I've ever made.These are amazing cars in my opinion. With so many options that are included in even the base models, truly impressive work the additional available packages. I was lucky enough to find a 2003 with 68,000 miles for just under $8,000... this was a couple years ago. It valued at $11,000 with all the options it has (convenience package, premium sound package, sport package, etc), and all values just about the same or a tad higher. With some of these options, you can adjust our turn off the traction control, or various other features in case you have s different driving requirement or style lol. Final comment on this; just a couple of days ago I was pulled over by a motorcycle officer running a speed trap. The very first thing he said to me was "Ok, so this obviously isn't a 2003... what's going on with it?" Lol you get that a lot with these cars.

Best bang for your buckThis is a sexy little sports car, great for if you’re new to sports cars but still holds its own in performance. The inline 6 has great acceleration while the smaller, lighter body is great for handling. Take this on a windy mountain road and you’ll feel like a race car driver(I recommend the manual trans for an authentic feel and better mpg/performance). Downside is the interior. Hopefully you’re not over 6 foot as you will not be able to fit in the car. Also lacks storage and good cup holders in the cabin. But overall it’s a great car, fun to drive and easy to modify.

Best bang for the buck you can get.Have had many sports cars through the years. This one is fun and reliable. The straight six sounds great and has quite a bit of low end torque. Get one.
