2004 Porsche 911 problems
The Porsche 911 (pronounced Nine Eleven or in German: Neunelf) is a two-door 2+2 high performance rear-engined sports car introduced in September 1964 by Porsche AG of Stuttgart, Germany. It has a rear-mounted flat-six engine and originally a torsion bar suspension. The car has been continuously enhanced through the years but the basic concept has remained unchanged. The engines were air-cooled until the introduction of the 996 series in 1998.
The 911 has been raced extensively by private and factory teams, in a variety of classes. It is among the most successful competition cars. In the mid-1970s, the naturally aspirated 911 Carrera RSR won world championship races including Targa Florio and the 24 Hours of Daytona. The 911-derived 935 turbo also won the 24 Hours of Le Mans in 1979. Porsche won the World Championship for Makes in 1976, 1977, 1978, and 1979 with 911-derived models.
In a 1999 poll to determine the Car of the Century, the 911 was fifth. It is one of two in the top five that had remained continuously in production (the original Beetle remained in production until 2003). The one millionth example was manufactured in May 2017 and is in the company's permanent collection.

I am 44 years old and have always wanted this car. It has far exceeded my expectations in almost every area! The handling is like a go-kart and the acceleration is like a rocket! The rear seat comes in very handy on those days when I have to take both children. For a top-down true sports car (unlike the SL 500), there is simply nothing better!

Your daily driver will command respect and turn heads with its quick acceleration. While it may come with a higher price tag, the tight handling and luxurious feel make it worth the investment. And who says a mid-life crisis has to be a bad thing? This car will make it something to look forward to!

Great to drive. Wish it got better mileage. People always ask me what I'm doing driving such a hot car, and a black one at that!
-
That's great to hear! It sounds like you really enjoy your car.

Within 1500 miles, I experienced an engine oil leak that took the dealer two months to identify and repair. Unfortunately, the car was also delivered to me with the radio not working, which took 6 weeks to repair. Although it was frustrating, I appreciate the effort put in by the dealer and Porsche to resolve these issues. Despite these challenges, I still believe my $140k investment was worth it.

Are you having problems with your 2004 Porsche 911?

The new 997 Carrera has received a lot of acclaim, but unfortunately, there seems to be a major design flaw. However, Porsche has made the process of removing the xenon headlamps even easier in the 2005 models. Unfortunately, some thieves in South Florida have caught on and have already helped themselves to this reviewer's lights, which cost $4,000 to replace. The staff in customer-commitment at Porsche North America also admonished this reviewer for complaining about this flaw.

Hey there! I noticed that the Porsche has a smaller engine compared to other models like the Mercedes SL55 and Nissan Maxima. However, it's important to keep in mind that engine size isn't everything when it comes to performance. Just wanted to share my thoughts with you!

I always dreamed of owning a 911, but unfortunately, my experience with it has not been as positive as I had hoped. While I still find the car's appearance and sound to be exceptional, I have been disappointed with its performance, especially considering its high price tag. In comparison to other cars such as the Corvette or BMW M3, the 911's performance falls short. Additionally, the car's reliability has been a major issue, requiring frequent trips to the repair shop. Finally, the introduction of the Boxster has somewhat diminished the exclusivity of owning a Porsche. For those considering purchasing a 911, I would advise admiring it from afar rather than making the investment.

For the price of the car, the interior should be a lot more luxurious. Unfortunately, there is no wood trim included unless you pay extra for it. When compared to MB or Lexus, this is a noticeable difference.
