I recently ran an analysis using AI of the 991 market, looking at listing price vs. sales price and specifically noting options and colors that commanded a higher sales price. As you’d expect, special, unusual, or PTS colors do command a higher price. There are obviously many other factors that impact sales price, but PTS definitely makes a difference.
My analysis was specific to 991 Turbo and Turbo S cars, but it’s relevant here too. Here’s an excerpt:
What specifically adds or subtracts value
Strong price drivers (premium features)
Low mileage (< ~10k miles) — consistently correlated with the largest premiums; low-mileage examples have sold for substantially more than similar-year higher-mileage cars. See 2019 low-mile Exclusive Series sales (~$290k+) vs standard 2017/2019 examples (~$140–160k).

Limited editions / Exclusive Series — large, often multiple-hundred-thousand-dollar premiums versus standard cars.

Porsche Ceramic Composite Brakes (PCCB), sport chrono, rear-axle steering, PDCC, center-lock wheels, and Paint-to-Sample / unique exterior colors— these options increase desirability and can push the sale price up, especially when combined with low miles and a documented history. (See BaT photos/spec lists showing PCCB, center-lock wheels and special paints on high-sale cars.)

Moderate/conditional drivers
Porsche Approved CPO status — buyers pay a premium for CPO because of the factory inspection and warranty coverage; it reduces buyer risk and typically shortens time to sale. The Porsche Approved program and warranty details are published by Porsche.

Service history & single ownership / no accidents — clean Carfax / maintenance history matters and often justifies a tighter price relative to otherwise similar cars. Many CarGurus listings emphasize “no accidents” as a selling point.

Negative price drivers
High mileage (>~30–40k), accident history, missing maintenance, or poor cosmetics lower selling price materially. Dealer asking prices will sometimes still be optimistic for such cars, but realized sale prices reflect these negatives.

Good morning. As someone who ordered a 991 in Brewster Green, I'm not sure? PTS drives a(n irrational?) premium on GT cars, but not sure the boost is similar on a Carrera or Turbo. Which PTS color seems to matter, but data is thin. I've kept loose track of 991.2s in Brewster in NA, and know of three C2 coupes, one C2S coupe, one GTS Cab, two GT3Ts, one Speedster, and two GT2 RSs. I'm sure there are more, but even if you 2-3x those numbers, it's slim pickings.
I'd value configuration/condition/seller over exterior color if I was looking for a 991.2 today, because my aim would be depreciating the car with high miles.
Brewster Green get 4 out of 5 paint cans review for rarity, however, I suspect it is not very popular. (everyone has different taste). Yes, paint to sample typically brings more money.
could depend on the actual color and having some patience?. unusual colors (certain browns, oranges, purples etc) aren't on as many shoppers preferred color choice lists vs more traditional colors. Smaller pool of potential buyer that would consider these colors.... but when the right buyer comes along, they could be willing to pay up. Don't see Brewster Green as an unusual color myself...just a beautiful dark/deep green that would appeal to many. Rare so i'd think yes to fetching a premium. Bright Lime green would be more of what i'm referring to regarding greens. Think this would apply to any car.....not just 911's.
However...If you're patient, someone will come along at some point and love your rare purple car and possibly even pay extra? =)
I can only speak from my own experience, which is anecdotal at best. When I was shopping for 991.2's C2S's last year, I had a fairly good feel for the market based on mileage, condition, and options. I was primarily focused on CPO cars. Highly optioned C2S's (Sport Package, Premium Plus Package, full leather, sunroof, and some other goodies) with sub 20k miles were going in the high $110's to $120k. I ended up finding my '18 C2S in PTS non-metallic Slate Grey with all of those options plus Bordeaux red seat belts, gauges, and sport chrono clock, carbon fiber package, Bose and a few other options with 13k miles on the odometer for $125k.
Obviously the color itself will determine the desirability. I feel like non-metallic Slate Grey makes my car unique, but it's still a conservative color that I think appeals to a wide group of potential buyers. Additionally, I feel like PTS on Carrera's seem to be a bit harder to find despite the higher quantity of Carrera's produced, compared to GT 911's and Turbo S's that seem to get PTS allocations more than their Carrera counterparts.
TL;DR - I think PTS colors on 991's will command a ~$5k to ~$7k premium, all things being equal.
I would pay a 10% premium for Irish green. I think for most Porsche guys that would be safe to assume. A MT now seems to bring a 15% premium on non high mileage cars. Again not correlated market data just me watching prices.
