I can still picture that late-summer morning when I test-drove a Samurai-blue 911 SC from 1979—my very first company run as a newly minted sales consultant at HUBRAUM. The air-cooled flat-six barked behind me, the steering wheel danced in my palms, and I knew: this isn’t work, it’s passion. Since then I’ve guided countless clients who wanted to buy a Porsche classic car. In this post I’m sharing my best insights, the biggest pitfalls—and how we at HUBRAUM make sure your dream 911 never turns into an expensive nightmare.
Why Porsche, of all marques?
- Racing DNA you can feel
Every Porsche—356, 911 or 924—carries genes from Le Mans and the Monte Carlo Rally. As early as 1963 the 901 (later 911) proved that everyday usability and motorsport DNA can coexist. - Timeless design
The 911 silhouette has been instantly recognisable for six decades—and precisely for that reason it remains eternally coveted. - Value retention
Air-cooled RS, Turbo and Speedster variants have quadrupled in value in the past 15 years. If you understand the technology and inspect the substance, you’ll discover an investment that pays a “driving-pleasure dividend”. - Parts supply
Porsche Classic lists tens of thousands of items all the way back to the 356; many parts are re-manufactured as “Re-Pro”—a huge edge over exotic brands.
The Downside—Putting Cards on the Table
| Era / model family | Persistent issues |
| Air-cooled era (356, 911 F/G, 964, 993) | Rust on sills & battery boxes · Magnesium cases pull head studs · 964: oil leaks at intermediate-shaft cover · 993: secondary-air passages clog—costly emissions test |
| 996 / 997.1 (1997–2008) | IMS bearing failure (1–8 %) · Bore scoring on 3.8-litre · Headlamp water ingress → ECU failure |
| Transaxle (924, 944, 968) | Timing belt & water pump every 60 000 km—or risk engine damage |
| 928 | Timing belt, oil-pump seal, brittle wiring looms—labour-intensive |
| Boxster / Cayman 986–987 | IMS, RMS & roof-drain issues—control units end up in a “foot bath” |
Costs many buyers underestimate
- Routine service at a Porsche Centre: €700–1,200 per year
- Engine rebuild after 997 IMS failure: from €12,000; edge cases > €25,000
- Insurance: collector 964 from €400, 930 Turbo / GT3 fully-comprehensive > €2,000
- Frame-off restoration of a 356: easily €120,000 +
My HUBRAUM Roadmap to a Worry-Free Porsche Purchase
- Fix model & budget
Together we compare price corridors from mobile.de, Classic-Data and club forums with actual sales at HUBRAUM. - Pre-inspection with diagnostics
Paint-depth gauge, endoscope and PIWIS tester. Bore scoring? We see it. Rust bubbles? We feel them. Fault codes? We read them. - Expert check
We can book a Porsche Classic Partner for a pre-purchase inspection (~ €500)—cheaper than any later surprise. - Calculate & negotiate
IMS replacement needed? Brakes due? We crunch the numbers transparently and deduct required work—so you buy without rose-tinted glasses. - Secure & register
Historic report, COA, valuation, personalised plates—all under one roof, including finance or leasing if desired. - Preserve value & enjoy
Seasonal checks, cavity wax, battery tending—our preservation service prevents storage damage and protects market value.
Personal Anecdote: The IMS Emergency on the A 9
A client phoned in panic: his freshly privately-bought 996 Carrera 4 was spluttering, warning light on—300 km from us. We collected the car in a closed trailer, opened the engine: IMS bearing collapse, metal shavings everywhere. Damage: €17,000. The same client now tells visitors in our showroom how, at the second attempt with HUBRAUM, he bought a silver 997.2—with reinforced bearing and pre-owned warranty. Trust is built when catastrophes are handled honestly.
Future-Proofing & Community
Since April 2025 Germany’s first Porsche Classic Center in Kassel bundles full restorations, original parts and factory valuations—just a three-hour drive from us. Add to that the world’s densest Porsche-club network; hardly a part exists that isn’t sleeping somewhere in the scene.
Low-emission zones? Still free with an historic H-plate. Youngtimers need the green sticker, but the federal government upholds grandfathering—bans on classics are seen as unlikely.
How HUBRAUM Minimises Risk
| Challenge | HUBRAUM solution |
| IMS, timing-belt, bore-scoring risks | ✔ Engine endoscopy, oil analysis, preventive bearing upgrade |
| Hidden paint or accident damage | ✔ Paint-depth report & chassis alignment check |

“Heritage Brand – Future Value” is not a slogan for us—it’s a promise. We sell only cars we would invest our own money in.
