Which car is more reliable, 550 or 575?

Both have had very good records. The 575 is more complex.

 

Yes.
Local guy/friend Tim K picked up a used 550, Brian Crall checked it out and recommended "Buy it". Tim did and now has over 25k miles on it, using it as his daily driver. He beams about this car and hasn't had any major problems, although it did have the standard shock issue resolved prior to his ownership.

 

There have been a lot of tweaks that make the 575 an improved vehicle. In a way it is more reliable as the fuel system has been simplified. A whole circuit was eliminated. The a/c circuit is simplified as well. Some switches are different. The leather dash was made more durable, less shrinkage problems. Some seals in the engine compartment seem not to leak oil and the starter motor is better shielded from heat. The cooling of the engine compartment is better decreasing internal temperatures (good for anything plastic or rubber). And the list goes on. The 550 is a good car but the 575 is much improved. I owned both.

I have made this decision a few times and gone back and forth from 550/575 and 996 TT.

The 996 TT is the best daily driver exotic on the market...Can the 550/575 be driven daily-yes. They are comfortable and reliable. They are more reliable the more they are driven (sounds strange but true). I would say the only reason to purchase a 575 at this point is if you want a F1 transmission. They also have a bit more depreciation in them. The 550's have pretty much hit the wall...

I also personally feel the 550 looks more aggressive than the 575 but that is just my opinion.

The costs of operating a 575/550 vs. the 996 TT is really up in the air (depending on CPO or not). Once the 996 TT are out of their warranty period they are also expensive to maintain however the quality control with Porsche is a bit higher so the parts do not seem to play such a large roll.

As far as driving the cars-the experience of the 550/575 is all there and they are equally as fast if not faster than the 996 TT (non mod). The exclusivity of the Ferrari is also there which is not with the Porsche. There are more Porsche TT around my area than you can imagine, I rarely see another Ferrari around and I drive my 550 everyday-unless I am driving my TT...

I love both cars and have owned and will own many more of both but the Ferrari takes the cake on true driver feedback.

 

I guess if you really want to know which one to buy the choice is obvious. the 550 with its superior race history will command more money years down the road. Its kinda like comparing the current pricing of 250GTO's to 275's. The 550 is lighter by about 300lbs., but both cars are a miracle and you will be in a dream world with either.

I bought a 575 F1 in January this year with 2.100 km on the clock and did another 36.000 km till today. The more you drive the better gets the engine and the whole car and last but not least the driver. Most of the time I was driving on the "Autobahn" in Germany and Italy and this was the right gym treatment to the engine. Oil consumption was only 05 - 1,0 liter per 10.000 km and the services were all done at Motor Spa at Modena.

The 575 is definetely smoother to drive than the 550 especially if its an 2005 model like mine which has the F1 software of the Scaglietti.

Always the "M" modell received the final, more civilized touch and lost some "wildness". So it came with the 456M and to the 575M happened the same.

The best is that every time I am shortly before reaching home I always try to find excuses to do another lap.

 

Whoops! sorry about the threesome!

 

With the greatest respect, (and appreciating that you have alternated between p- and f-cars) I think there may be a touch of subjectivity there.

I would beg to differ on which is faster, whether in a straight line (which to my mind is largely irrelevant, but is important to some people), or more importantly on track. There is no contest, much as I hate to say it as a 550 owner. The TT is lighter by the equivalent of a couple of really fat guys, and its engine layout means it generates enormous traction out of bends. Naturally if you catch the TT off boost in a straight line, the 550/575 can immediately surge ahead, since throttle response is immediate and vicious. But that turbo will eventually reel you in....

(As an aside, I am very doubtful about the published 550 top speed - maybe the 575 is truer, but from experience I find that Porsches are sometimes underquoted by the factory. For example, my current (stock) GT3 is quoted at 380hp but seems to be putting out something closer to 400).

Feedback is a combination of factors, all dependent on subjective personal opinion. For me "feedback" and the whole sensory experience is (in rough order of priority):

- steering feedback, weighting and tactility
- progression of slip (can be very tyre dependent, but the chassis fundamentally plays a part)
- throttle response and drivetrain smoothness
- gearbox shift (tactility, weight and speed of shift)
- brake response and ability to modulate
- clutch weight and tactility
- aural feedback
- ergonomics

Again, in my very personal opinion, the 550 scores very highly all round, but I don't think it's a clear cut case against the TT. In fact, although on balance I would say the sensory experience in a 550 is more enjoyable, I do find the steering feedback slightly lacking (which for me is paramount). I suspect the V8 models are a lot better in this regard, but I haven't driven them extensively.

Either way, they are great cars!

I owned and drove my 575 for several years. It is the consumate daily driver. The F1 is excellent and if you are seriously going to use it as a real daily car, the F1 is the only way to go in urban traffic. (I'm assuming the 575 you are considering is F1).

The comparison made earlier re 250 GTO and 275's is spurious. The real comparison here is 275GTB's to the enhanced 275GTB/4's. The 550 is is simply the earlier version of a 575 and in my opinion, a lesser car. I would bet any amount of money that in 30 years and more 575's will always fetch more than 550's.

In considering the cars today there is a real discount for a 550 versus a 575 and that accurately reflects the gap between the cars. I think the 550 is a wonderful car but the 575 is far more user friendly and in terms of service and maintenance there are no significant differences other than the F1.
