ABOUT

Stewards of the marque.

Zuffenhausen Keys is a private Porsche advisory. We represent considered sellers and serious buyers with discretion, expertise across every era of the car, and a standard of presentation usually reserved for the auction stage.

THE STORY

Where exceptional cars find their next custodian.

I'm Mason Gilchrist.

I've loved cars for as long as I can remember. Growing up, I was the kid who could recognize almost anything on the road, fascinated by the engineering, design, and stories behind every car.

My Porsche journey began in 2012 while I was studying Kinesiology in college with plans of becoming a physical therapist. That same year, my dad bought his first Porsche, and everything changed. The more time I spent around the brand, the more I fell in love with its heritage, engineering, and the incredible community that surrounds it.

That passion eventually became Zuffenhausen Keys.

I created Zuffenhausen Keys because I believe exceptional cars deserve exceptional representation. Selling a Porsche isn't just about finding a buyer...it's about understanding the car, telling its story, and connecting it with someone who will appreciate it as much as its previous owner.

Today, I specialize in representing Porsche while also working with select exotic automobiles. Every client, every car, and every relationship is approached with the same philosophy: honesty, transparency, and attention to detail.

Because exceptional cars deserve more than a listing.

They deserve the right next custodian.

WHAT WE BELIEVE

Principles that hold their value.

01

Expertise across eras

Air-cooled, water-cooled and modern GT cars are valued by different logic. We know which levers move each.

02

Evidence over emotion

Every number we advise is anchored in real, recent sold results — defensible to the last dollar.

03

Transparency wins

An honestly-described car outsells a flawless story. Disclosure builds the confidence that drives bids.

04

Discretion always

Quiet representation, private networks, and a sale conducted with the privacy a collector expects.

We begin with a candid valuation and a clear plan: what to correct, what to document, and what to disclose. We assemble the file, commission the presentation, and choose the route and timing that suit the car — not the calendar.

Through the sale, we manage the enquiries, answer every buyer question with evidence, and negotiate to protect your position. The owner stays informed and unburdened; the car is met with conviction.
