If there’s one sports car marque with a devoted following willing to pay prices that are sometimes hard to believe, it has to be Porsche. And Broad Arrow’s 2026 edition of its Porsche-only auction—called Air|Water and taking place in Orange County, California, on the 25th of this month—makes that crystal clear once again.

A wide selection of Porsches is offered for sale, with some heavily modified and far-from-standard cars commanding the highest estimates. It doesn’t seem to matter much who worked on them or what exactly was done—modifications, tribute builds, bold graphics, and bespoke interiors all appear to increase these cars’ values.

The king of Porsche customs—at least in terms of price—has to be Singer, and one of its creations is present here. It’s a 1990 coupe, significantly wider than standard, and fitted with all the bells and whistles in both the engine bay and suspension. The interior arguably stands out the most, featuring color-coordinated leather and suede, along with Apple CarPlay and a sound system worthy of Carnegie Hall. The car has had two owners since being “reimagined” in 2022 and has covered just 1,499 miles since. The estimate? $1.0–$1.3 million. We’re not making this up.

But wait. A smurf-blue 2025 Porsche SCR by tuner RUF is expected to fetch an even higher $1.9–$2.3 million. Then again, this car features a carbon-fiber monocoque body and Kevlar-carbon bucket seats, contributing to a total weight of just 1,250 kilograms. Combined with its high-spec 4.0-liter engine, it delivers a 0–60 mph time of 3.4 seconds. The owner, who commissioned the car to his specifications, has driven it just 217 miles since delivery last year.

A 1975 911 S, built to resemble a 911 RSR by Gunnar Racing—with megaphone exhaust, center-lock wheels, and a livery that looks straight out of a 24-hour race—is estimated to sell for $250,000–$350,000.

Looking for something more standard? A red 1957 356 A Speedster with matching numbers that has spent its life in Southern California seems almost affordable at $300,000–$350,000, while another 1958 example in silver gray with green leather is expected to bring $425,000–$475,000. A 1980 911 SC Coupe in an attractive shade of blue carries an estimate of $75,000–$90,000. Perhaps that’s the one to go for—before the tuning scene gets to it.
