A 2007 Saab 9-5 Aero fitted with a documented Hirsch Performance upgrade has appeared for sale in Germany, carrying a €20,000 asking price and one distinction that immediately separates it from the usual Aero listings: it is currently the only first-generation 9-5 on AutoScout24 explicitly advertised as a Hirsch-developed 300 HP version.
The Smoke Grey/Smoke Beige Metallic sedan is being offered by a dealer in Stelle, near Hamburg. It was first registered in January 2007 and has covered 246,493 kilometers, so this is not a low-mileage collector car preserved under a cover. Its value proposition rests elsewhere: an unusual factory-approved performance specification, surviving Hirsch components and, according to the seller, a complete set of certificates and supporting documents.
From 260 to 300 PS
The standard 2007 Saab 9-5 Aero used the 2.3-liter turbocharged B235R engine with 260 PS. Hirsch Performance, Saab’s official tuning partner, offered an approved upgrade that raised output to 300 PS, with power transmitted through either a manual or automatic gearbox.
This particular car has the five-speed automatic transmission and is listed with 221 kW, exactly matching 300 metric horsepower. The seller describes it as an original “Hirsch Performance Paket” car rather than a later independently remapped Aero.
That distinction matters. Many surviving 9-5 Aeros have received software upgrades from various tuners, but the Hirsch program occupied a different position. Hirsch modifications were offered through the Saab dealer network, accompanied by homologation documents and developed to retain compatibility with the car’s existing safety, diagnostic and servicing systems. Hirsch continues to describe its Saab engine upgrades as dealer-programmable packages designed to preserve normal drivability and servicing requirements.
The Wheels Confirm Part of the Story
The dealer’s equipment list describes the car’s wheels simply as 18-inch Saab Aero alloys, but the photographs show something much more specific: the original six-spoke Hirsch Performance design.
These 18-inch wheels were developed for the earlier Saab 9-3 and 9-5 and have become increasingly difficult to find in good condition. Their wide, slightly sculpted six-spoke layout is distinctive enough to identify even without visible Hirsch rim decals. Saab vs. Scepticism, which has documented several sets during restoration projects, describes them as the original Hirsch 18-inch six-spoke wheels intended for early 9-3 and 9-5 models.
The seller also lists a Hirsch Performance exhaust system, giving the car at least three identifiable parts of the conversion:
the 300 PS engine upgrade, the Hirsch exhaust and the six-spoke Hirsch wheels.
The advertisement does not confirm Hirsch brakes, springs, dampers or an upgraded intercooler. The “sports suspension” entry could refer to the standard Aero chassis rather than an additional Hirsch component. The accompanying certificates should therefore determine exactly how extensive the original conversion was.
A High Price, but Not an Arbitrary One
At €20,000, the asking price is well above that of an ordinary high-mileage 2007 Aero. AutoScout24 currently shows standard 260 PS examples from the same year at substantially lower prices, although those cars generally have even higher mileage and far less unusual specifications. The same search results also include a 280 hp 9-5 Troll and several later-generation 9-5s, but no other classic 9-5 Aero advertised with the corresponding 300 HP Hirsch specification.
The mileage prevents any simple comparison with low-use collector cars. At nearly 250,000 kilometers, the condition of the automatic transmission, turbocharger, timing components, suspension, cooling system and body structure is more important than the Hirsch badge alone.
However, the dealer claims that the car has a full service history, has not been involved in an accident and remains covered by a German inspection valid until April 2027. A 12-month warranty is also included, an unusual feature for a 19-year-old performance Saab with this mileage.
Its specification remains strong even without the Hirsch components. The car has black leather upholstery, heated and ventilated front seats, dual-zone climate control, xenon headlights, the original Saab navigation system and a wood-trimmed dashboard. It is a late first-generation Aero sedan with the equipment buyers generally seek, rather than a basic 9-5 later upgraded with isolated performance parts.
Not the First €20,000 Hirsch 9-5
SaabPlanet previously covered another 2007 Saab 9-5 Hirsch with 300 hp, offered in Romania in 2023 for approximately €21,500. That manual-transmission car was described as having received a far more extensive conversion at Hirsch headquarters, including upgraded brakes, suspension, intake, exhaust, wheels and software.
The German car is different. Its listing does not claim the same comprehensive Troll-style package, and its 246,493-kilometer odometer reading changes the calculation considerably. What it offers is a potentially more restrained and usable version of the Hirsch formula: a late 9-5 Aero sedan, automatic transmission, the approved 300 PS engine conversion and some of the most recognizable wheels ever produced for the model.
The €20,000 price will ultimately depend on what the paperwork confirms. If the certificates match the car, document the engine conversion and establish that the visible Hirsch parts were installed as part of the original package, this is not merely another tuned Aero wearing rare wheels.
It is currently the only example of its exact kind on AutoScout24 – and possibly the clearest test of how the European market now values a documented Hirsch 9-5 after nearly a quarter of a million kilometers.
Just bought a 2009 Saab 9-5 wagon for $2500 with 95K miles. Hi from Ohio.
Sounds like too much. I had one like that, 300 hp Hirsch (that included the hardware), Hirsch brakes, wheels, suspension etc, custom leather interior. What a fantastic car. If I still had it it would have done over 400k kms by now. Sold it (worst decision as far as cars go) in 2012 at 172k kms.
