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.

This is one of those cars that you can't help but fall in love with over time. The longer I've owned it, the more I've come to appreciate its looks and performance. I say this because I wasn't very knowledgeable about the 911 when I bought a 4S (to replace my beloved Lexus SC400 which was totaled out). I've always liked the 911 style, but had little knowledge about it. However, after doing my homework and learning about the many pros and few cons (mostly headlight styling and IMS bearing failure), I ended up with an immaculate 4S for less than the price of a new Prius. It has been very reliable. Aside from routine maintenance, in 3 years I've only had to replace the battery, an oil pressure sender, rear brake pads, and a power steering hose. The IMS had been changed by the prior owner. I love looking at it in the garage. It is a classic now, despite what others may say. I still get excited firing it up, accelerating like a bat out of hell, and taking it through its paces on twisty roads. This was a $90K+ car new and the value is still there. Downsides? Yeah, the cost of maintaining and repairs can be high, but so far I'm good with it and I can do some of the work myself. It is not the rolling lounge chair my Lexus was. Seating is great, but there's more road feel and noise. Oddly, one comes to appreciate that feel as a reminder of the racing beast within. It's a combination of rawness and refinement. Keep an eye on the rear tires as they wear quicker than normal cars. My car is pristine and I tend to be careful where I park it, so you may want to have an alternative vehicle for supermarket trips. I guess the highest accolade I can give is that I have no plans to buy a newer one and intend to keep this for a long, long time.

I hope you're doing well! I wanted to share my experience with my Porsche with you. After test driving every model from the 993TT, GT2, GT3, Targa 996, and Carerra 997 with everything else in between, I decided to buy this Porsche second hand. For the money, I think this Porsche is amazing! It's fully loaded with everything Porsche could throw into a car, plus additional HP with X51 Power Boost. It's a joy to drive with incredible handling, acceleration, and a smooth ride. The color outside is beautiful and the all-leather interior is top quality. The only downsides are the usual complaints...bad cup holders and the 996 narrow body. Otherwise, I have no regrets with this purchase!! If you ever get the chance, I highly recommend test driving one!

The GT3 is a 100% performance vehicle that offers a thrilling driving experience. While the price of these cars has remained stable due to their limited production, it's worth every penny. The car demands your full attention and correct driver input, making it a true driver's car. It's important to note that the GT3 doesn't have any electronic traction control or stability management aids, sunroof, or rear seats, providing a raw and authentic 911 driving experience.

Over the past year, I had the opportunity to test drive and research every Porsche made from 1996-2007. After careful consideration, I decided to go with the 2004 Anniversary model. I absolutely love its price, acceleration, styling, engine sound, aggressive exterior, and interior creature comforts. It offers the most value for the money without the added expenses of a turbo, which I plan to get with my next Porsche, a 993TT. Maintenance has been minimal, and the fuel economy is exceptional for a sports car. Everywhere I go, heads turn, including from other Porsche drivers who are curious about the type of Porsche I'm driving. It's a unique Porsche that packs plenty of horsepower.

I recently purchased a Porsche (Targa) after contemplating it for a while. Looking back, I wish I had made the decision sooner. If you are anything like me, you may spend countless hours analyzing the price and performance and trying to justify the cost. However, if you have the means, I highly recommend buying the Porsche of your dreams without hesitation. I chose the Targa for its unique and stylish appearance, as well as the open feeling and extra headroom it provides. The power-roof works flawlessly, and there is minimal wind or road noise. It's difficult to put into words the experience of driving this car, as there is simply no comparison to any other street vehicle.

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.
