Fewer cars. More attention.
We accept a limited number of cars each week, so every one receives the time it deserves.
No queues, no upsell. A clear diagnosis, a written plan, and work carried out to the manufacturer’s specification. You will always know what was done, and why.
Diagnose first
Manufacturer-level scan tooling and methodical testing before a single part is ordered.
Correct, not convenient
OEM or OEM-equivalent parts, specified fluids, published torque values.
Returned as expected
Detailed records, photographs on request, and a car that leaves cleaner than it arrived.
Six disciplines, one standard.
From a first scan to a full chassis refresh, every commission is scoped in writing before work begins.

Precision Diagnostics
Manufacturer-level scan tooling, live data and guided testing, to find the cause rather than the symptom.

Sympathetic care for air-cooled, carbureted and early-electronic European cars.
Discover
How a visit unfolds.
Unhurried and transparent, from first conversation to handover.
Consultation
A conversation about the car, its history, and how you use it.
Assessment
Inspection and diagnostics, with findings explained plainly.
Written plan
A clear estimate, prioritized. Nothing proceeds without approval.
Handover
Road-tested, documented, and returned ready for the drive home.
Your car, given the attention it was engineered for.
