Why Choose Sierra.

A Privately Curated Fleet

Each motorcar is privately registered, dealer-serviced on schedule, and presented detailed before every handover. No third-party listings, no part-time partners.

Door-to-Door Delivery

A liveried driver presents your vehicle at your residence, office, or private terminal — detailed, fueled, and complimentary within a fifty-mile radius of every residence.

Reservations By Request

Our concierges arrange every element — dates, route, residence, itinerary — discreetly and without intermediaries. Most inquiries receive a curated short-list within the hour.

Held In Confidence

Comprehensive coverage on every reservation. No company decals, no bumper plates, no marketing photographs. Your booking and identity remain entirely your own.

Founding Season · MMXXVI

Welcomed first. Driven further.

Our founding members receive complimentary delivery, a welcome detail, priority on weekend releases, and ten percent off their first reservation — a small thank-you for the introduction.

Members & Drivers

Words from the houses we serve.

Delivered to the residence on a Friday afternoon — kept the same way the day we returned it. The way a private rental should feel.

A wedding weekend in Newport. Two cars, two states, one call. They handled everything from coast to coast without a single follow-up.
