How Expensive is It to Maintain a Porsche 911?

Porsche 911

For as long as I can remember, I’ve had pictures of Porsche 911s on my walls. The car is the embodiment of perfection on the road. I always wondered how expensive they would be to maintain if I ever got my hands on one. Well, today I’m going to answer that question.

The costs to maintain a Porsche 911 will vary from year to year. From years 1 to 5, expect to pay between $350 and $7,500 annually in repairs and maintenance. The number might seem high, but it’s comparatively very low to the overall value of the vehicle, which starts above $100,000.

I’ll cover how expensive it is to maintain a Porsche 911, I’ll compare it to the overall cost of the vehicle, and I’ll determine if the maintenance costs are worth it. Let’s get started.

What’s So Great About a Porsche 911?

I realize that people might not understand the beauty of a Porsche 911. If you ask a car guy to list the best cars on the road, be prepared to hear the Porsche 911 pop up on that list.

It’s high-performance, high-octane, German engineering. The car is a timeless beauty that can’t be compared to anything else on the road. It’s perfectly balanced and lightweight so the high horsepower is even more meaningful.

It’s a car that doesn’t change unless there’s a technological improvement in the market — sort of like a Rolex in the car world.

Until driving a Porsche 911, it’s hard to understand how perfect they are.

Price to Buy a Porsche 911

Before diving into maintenance costs, I want to talk about the cost of purchasing a Porsche 911. I think it will give a good frame of reference so you can compare the costs appropriately. A $500 maintenance bill on a $3,000 car is a lot different than the same bill for a $30,000 car.

According to Porsche’s site, you can sit in a new 911 Carrera for $101,200 or grab a fully-stocked and loaded 911 GT3 w/ Touring Package for upwards of $220,000.

Keep these numbers in mind as you read on.

What Type of Maintenance Is Required?

Now, let me talk about some specific maintenance. These are a few key items that will pop up within the first 100,000 miles of owning and operating your Porsche 911. These are all required if you want to maximize the life of your car.

Oil Change

A routine oil change is a quick way to extend the life of your car. The frequency of oil changes will vary depending on your car and what type of oil you’re using. For full-synthetic oil in a newer car, you can expect an oil change every 10,000 to 15,000 miles or once a year.

Estimated cost: $200

Engine Air Filter

Next up is the engine air filter. This is another common piece of maintenance. Expect to change this every 20,000 miles or roughly once every 2 years.

If you didn’t know, this filters the air that flows through your engine. It keeps dirt and debris out of your engine — things that would otherwise hurt the performance and potentially kill your engine.

Estimated cost: $150

Brake Fluid Flush

A brake fluid flush will purge all the air out of your brake lines and replace the lines with fresh brake fluid. This is needed to optimize the braking performance of a Porsche 911. Expect to perform it every 2 years or so.

Estimated cost: $250

Spark Plugs

Spark plugs are a part that people commonly forget about. With bad plugs, your car can have trouble starting or you might notice some nasty shaking throughout the vehicle.

Luckily, the repair is pretty straightforward and only needs to be done once every 40,000 miles or 4 years.

As mundane as the replacement is, it’s pretty pricy in a 911.

Estimated cost: $800

Transaxle Fluid

Topping off fluids is something you’ll need to think about as your car gets older. Specifically, the transaxle fluid needs to be replaced after 10 years or 100,000 miles. If you’ve had your Porsche that long, you’ll notice more frequent repairs and maintenance at this point.

Estimated cost: $400

Brake Pads and Rotors

The wear rates on your brake pads and rotors will vary a lot from driver to driver.

A conservative driver will get about 10,000 to 20,000 miles on their brake pads before they need to be replaced. As far as the rotors, those can last 50,000 to 70,000 miles unless they get warped along the way. If your car is shaking when you brake, then it might be time for new pads and/or rotors.

Estimated cost: $2,100 combined

New Tires

All that horsepower under the hood of a 911 means nothing without some high-performance tires. These tires will wear at about the same rate, needing a replacement every 5 or 6 years. The cost, however, will be higher than a standard set of tires.

Estimated cost: $3,000 for four tires

Looking at Porsche’s Reliability

Another gauge of a car’s expected maintenance costs is how reliable the car is. In this case, the Porsche 911 has a reliability score of 72 out of 100. By definition, this is “average” — nothing too impressive.

This low rating isn’t great news for Porsche owners. It means more frequent breakdowns, unexpected replacements, and repairs in general. All of these equate to dollars flying out of your pocket.

Annual Maintenance Costs

Each year, the cost to maintain a Porsche 911 goes up. This is the case for almost every car since more things go wrong as time goes on. Here’s roughly what to expect in the first 5 years of owning a 911 as according to Edmund’s True Cost of Ownership guide.

Maintenance Costs in Year 1

The first year should be pretty uneventful. A handful of oil changes and some tire love should be the extent of things. The average maintenance for year 1 works out to about $364.

Maintenance Costs in Year 2

Year 2 is another inexpensive year for the 911 owner. Edmund’s report found that owners paid an average of $377 in maintenance for year 2. In addition, there are about $1,328 in repairs that you can expect to pay.

Maintenance Costs in Year 3

The price starts ramping up in year 3. Owners report spending $5,717 in maintenance and $2,041 in repairs for the calendar year. For reference, this would be the 2019 Porsche 911 purchased in 2018 being driven in 2021.

The maintenance cost is higher this year because the expectation is that the owner will go through the 40,000 and 50,000-mile service checks which are both expensive.

Maintenance Costs in Year 4

Actually, the fourth year is a little less expensive. This year, you’ll pay about $3,081 in maintenance and $2,198 in repairs.

Maintenance Costs in Year 5

Year 5 is about the same as year 4. Expect to pay $2,255 for maintenance and $2,363 for repairs.

Are the Maintenance Costs Worth it?

After giving you all these numbers, you’re probably wondering if it’s worth it. In my opinion, owning a Porsche 911 is definitely worth the required maintenance costs.

Think about it — you’re spending about 2 grand on a car that costs over 100 grand. The scale of everything is a lot larger and more expensive when you’re talking about Porsches.

In general, you probably don’t want to purchase one of these vehicles if you’re afraid of making some big purchases along the way. Since the components are high-precision and high-quality, you’re going to spend a lot more on replacements and repairs. Sometimes you’ll need to go to a shop that specializes in Porsches, which is even pricier.

From an objective stance, spending 2% of the car’s value in maintenance each year is totally worth it. It’s just a matter of how comfortable you are with needing to suddenly drop thousands of dollars on a repair.


As you can see, the maintenance costs for a Porsche 911 aren’t as bad as you might think. Before digging into it, I expected that owners were paying like 30 grand a year to maintain their car. I’m as surprised as you are. For more coverage on car topics and questions, check out the rest of my site. Be sure to look at my list of recommended car care products.
