Hello, I'm new.
 

I don't know the car but it looks practically new going by the pictures. The price does seem on the high side but is no doubt related to the low mileage. It's only been driven about 1,000 miles a year since new. Pretty car and not a lot of guards red C4S's around.

I find cargraphs.com useful for understanding pricing, especially versus milage: https://cargraph.com/usa/porsche/911/2010

Porsches depreciate at around $0.50/ mile. (Broad statement here. They depreciate faster with lower miles, slower with higher miles; and at different rates depending on initial price. But as a very rough guide: $0.5/mile.)

So when you are looking at a car with only 8K miles, compared to cars with $48K miles, the depreciation difference alone will be on the order of $20K.

Sure wish that was a good reference. Doesn't compute on my current car though or on my previous 997's either for that matter. My GTS had an original sticker of $118,000. It has 58,000 miles on the clock now so at 50 cents a mile that would only take $29,000 off the sticker resulting in a current value of $89,000. Actual value of my GTS seems to be somewhere in the $65,000 to $70,000 zone which brings the depreciation number closer to $0.90/mile than to $0.50/mile.

Very low miles and 6 speed manual transmission. If your pocket book fits. That’s a great ride and price.

I was NOT saying that $0.5/mile predicts value/price. I was saying that is the slope of the regression line for cars of the same year/model/trim. I.E. draw a graph of asking price for a bunch of cars of the same year/model/trim, but of different milage, price on the Y axis and milage on the X axis. Note that prices are not random; they decrease with milage. The slope of that line is roughly $0.5/mile.

So if you are looking at car A at it has 20K miles, and car B (same year/model/trim) has 30K miles, car B should cost about $5K less, just based on the fact it has more milage. And higher milage cars are worth less at a rate of about $0.5/mile. Again, the rate is more for lower milage cars and less for higher milage cars.

Realize it's not an exact science. Was just going by this summary of yours: "But as a very rough guide: $0.5/mile." Again, this is based on the three 997's I've owned and that number seems to be closer to about $0.90/mile, at least around the 40,000 to 50,000 mile point. I'm sure that number drops as the miles pile on but where does it drop to $0.50/mile and doesn't it start to increase again at some point? A 997 with 150,000 miles or more is a tough sell to a lot of customers unless very cheap.

I think you are not understanding the point regarding "slope".

I am not saying that if you bought a car that was worth $100K, and drove it 20K miles, that it would be worth $90K ($100K - (20K miles * $0.5/mile))

What I am saying (see chart below) is that when comparing cars of different milage, they differ by around $0.5/mile. Note the red line below, the slope is: ($70K-$50K)/(50Kmiles - 10Kmiles) = $0.5/mile. (The line below was not an actual regression fit, but placed to make the calculation easy and work out to exactly $0.5/mile).

And, accordingly, a higher milage car should never be worth more than a comparable lower milage car.

I brought this up because the OP was saying the price seemed high, but maybe that was due to low milage. Thus I was suggesting a way to normalize for milage differences between otherwise comparable cars.

I understand your slope and your reasoning. What I don't understand is the one yellow dot at $100,000 for a car with what looks like about 27,000 miles when everything else with roughly the same mileage is clustered around $60,000.

I believe that is a great car for a very good price. Finding a beautiful 997.2 4S 6 speed coupe is not as easy as one might think. I own one and if I were to sell it, I would advertise it for $70K. Mine has PSE and the Turbo wheels.

Thanks much for the informative posts. Question to myself is, am I willing to let go of my Alfa? You wouldn't think there would be such an attachment.............

I forgot to ask: Is there anyone around the New Hyde Park, NY(east of Queens and south of the LIE) area that y'all know of that can be trusted to do a PPI? thanks again.

Anybody? I heard one suggestion was to have the local Porsche dealership inspect the car. That sounds like letting the fox into the hen house. Don't think I want to go there. I would appreciate any feedback from anyone in the Long Island NY area. TIA.

My local dealership have done all my PPIs, at the end of the day they want your business but it's up to you where you go to have any service done. For me i prefer doing my own service to ensure its done right and nothing is over filled or not tightened or stripped out. As far as your original question pertaining to the '10 997.2 4S i believe the price is well within reason solely based on the mileage. It may seem high for a 997 gen 2 but It is a 4S with less than 9K miles.
