Some cars are
worth keeping.
The daily drive. The weekend Porsche. The one you’ll never sell. Give it the attention it needs, from a service to a full engine rebuild.
Talk to the workshopFor people who want to keep driving their car.
Tim Chandler and Jez Parsons run an independent workshop at Monks Gate, just outside Horsham. German cars come here for servicing, fault-finding and the mechanical work that takes a little more understanding.
01 / The work
View all servicesAn oil change. An engine out. And everything between.
A service due, a noise you can’t place, a car that isn’t pulling as it should. Start with what you’ve noticed. The workshop will take it from there.

Servicing & maintenance
Keep the everyday miles uneventful.
Diagnostics & fault-finding
Find the cause before replacing the parts.
Engine repairs & rebuilds
For the work that starts where a service ends.
Wheel alignment
Hunter 3D geometry, carried out in-house.
Suspension & performance
Get the feel of the car right.
Porsche, classic & race preparation
Road miles, weekend drives and days on circuit.
02 / The people
A workshop with Porsche in its history.
GCS has worked from Monks Gate since the mid-1980s. Tim and Jez’s story runs through Carrera Performance, the Porsche specialist that operated from this same site.
That mechanical background still shapes the work here. The workshop that takes a flat-six apart also looks after the Audi you take to work.

Five familiar badges. Decades under the bonnet.
911, Boxster, Cayman, Cayenne, Macan, and air-cooled classics
A flat-six needing attention, a classic coming out of storage or a service before the next long drive. Porsche work here draws on the workshop’s Carrera Performance history.

- Air-cooled 911 and classic Porsche mechanical restoration
- PDK transmission servicing
